-s

• IPA^(key): /s/ (after a voiceless consonant sound /p, t, k, f, θ/)
• IPA^(key): /z/ (after a vowel sound or a voiced consonant sound /m, n, ŋ, b, d, ɡ, v, ð, l, ɹ/)
• IPA^(key): /ɪz/ (after a sibilant consonant sound /s, z, ʃ, ʒ, tʃ, dʒ/—usually written -es)
  • (weak vowel merger) IPA^(key): /əz/
• Homophones: -'s, 's

Inherited from Middle English -s, -es, from Old English -as, nominative-accusative plural ending of masculine a-stem (i.e. strong) declension nouns, from Proto-West Germanic *-ōs, from Proto-Germanic *-ōs, *‑ōz, from Proto-Indo-European *-es, *-oes (plural endings). The spread of this ending in later Middle English was once argued to have been the result of Anglo-Norman influence; however, -as was already the most common Old English plural marker (used in approximately 40% of Old English nouns), and was initially more common in the North of England where French influence was weakest, only later gradually spreading south, replacing the usual southern plural ending -en. Cognate with Scots -s (plural ending), Saterland Frisian -s (plural ending), West Frisian -s (plural ending), Dutch -s (plural ending), Low German -s (plural ending), Danish -er (plural ending), Swedish -r, -ar, -or (plural ending), Icelandic -ar (plural ending), Gothic -𐍉𐍃 (-ōs, nominative plural ending of a-stem masculine nouns). Not directly related to German -er (plural ending) which has a different origin.

-s

2. Used to form regular plurals of nouns.

   one computer → five computers

4. Used to form many pluralia tantum (nouns that are almost or entirely without singular forms).

   shorts

   sunglasses

6. When appended to a number ending in at least one 0, expresses a range of numbers which share the digits before some or (usually) all of the 0s; frequently used for decades, centuries and temperatures.

   We often look back on the 1960s [the years from 1960 to 1969] with rose-tinted glasses.

   The Industrial Revolution went into full-swing during the 1800s [the years from 1800 to 1899 – but see usage notes].

   The temperature today will be in the low 30s.

   He placed in the 200s in the end.

• (regular plurals): In semi-formal or formal contexts, where the plurality of a noun depends on some unknown aspect of the sentence, the s may be parenthesised: "The winner(s) will be invited to a prize ceremony."
• (number): Decades formed with -s are usually pronounced as if they were written as two separate numbers. For example, 1970s is read as nineteen-seventies, as if it were written as 19 70s, not as *nineteen-hundred seventies or *one thousand nine hundred and seventies.
• (number): When the number before the -s ends in more than one zero, there is ambiguity about the range of numbers that is meant. For example, 1800s could mean "the years from 1800 to 1899; the entire 19th century" or "the years from 1800 to 1809; the first decade of the 19th century". The intended meaning can usually be derived from context.

The translations below are a guide only. See individual words for precise translations.

From Middle English -(e)s (third-person singular ending), from Northumbrian Old English -es, -as (third-person singular endings). Gradually replaced the older -eth, from Old English -(e)þ, -aþ, during the Middle English and Early Modern English periods.

It is predominantly believed that -(e)s is identical to the Old English second-person singular ending -es, -est (cf. archaic Modern English -est, as in thou singest). The use for the third-person singular would have been caused by speakers of Old Norse who switched to speaking English and confounded the endings due to analogy with their native tongue. In Old Norse, the second and third person singular indicative forms were identical (e.g. þú masar, hann masar; þú þekkir, hann þekkir; etc.).

An alternative theory sees the shift from /θ/ in -eth to /s/ (later /z/) in -(e)s as a mere phonetic simplification due to the frequency of the ending, but the objection to this is that no such development can be observed anywhere else in English. Nevertheless the relative similarity in sound between both forms may have facilitated the spread of -es.

-s

1. Used to form the third-person singular indicative present tense of verbs.

   to eat → he eats

• In Standard English, the -s suffix is only used to mark the third person singular present of verbs; however, in some varieties of English, particularly northern English, Scottish, US Southern and AAVE, the -s can be extended to other persons/numbers as well, as in: I eats me spinach; I hates the Yankees; they likes it here; etc.
• As in modern nonstandard varieties, the -s suffix can be used to mark the third-person plural in Early Modern English. However, it is less common than the modern standard zero ending, and is frequently only found in restricted contexts; for instance, Shakespeare only uses it where a plural subject has "singular" semantics.^[1]

From Middle English -es, from Old English -es, the masculine and neuter genitive singular ending of strong nouns. More at -'s.

2. Used in the formation of certain English adverbs.

   ‎forward + ‎-s → ‎forwards

   ‎downward + ‎-s → ‎downwards

   ‎alway + ‎-s → ‎always

   ‎sometime + ‎-s → ‎sometimes

   ‎betime + ‎-s → ‎betimes

   ‎beside + ‎-s → ‎besides

   ‎evening + ‎-s → ‎evenings

   ‎unaware + ‎-s → ‎unawares

• -st

A variant spelling of -'s, partly an archaism, partly by dropping the apostrophe.

• -'s (on pronouns; now nonstandard)
• -es (obsolete)

-s

1. (on pronouns) Possessive marker, indicating that an object belongs to the word bearing the marker.

   hers; its; ones (now one’s); theirs

   (neopronouns): eirs; hirs; pers; thons; xyrs; zirs

2. (on nouns, now nonstandard) Alternative form of -'s

   devils doorbell; dogs-bane; St. Marys; (obsolete) kings

• In most cases where -s is found nowadays as a possessive case marker, it is a simple misspelling of -'s. However, possessive determiners derived from personal pronouns use -s (e.g., its, not it's). The same is true of pronouns derived from possessive determiners (e.g., theirs, not their's). The possessive form of who takes -se (whose, not who's).
• Bare -s is used in some business names that derive from possessive family names, e.g., Barclays and Harrods, but compare Sainsbury’s; compare Wikipedia's article on possessives in business names. In speech, /z/ (or /s/) is sometimes added to business names which have neither -s nor -'s in writing, resulting in s-forms, which see.
• Sometimes used in place names; e.g., Harpers Ferry (formerly spelled “Harper’s Ferry”), Queens County (note that the former name of County Laois was officially “Queen’s County”, however, the apostrophe-less spelling is well-attested).

Modern sense in slang . According to OED, a colloquial clipping of the hypocoristic diminutive suffix -sy. As AHD writes, -sy itself usually being informal, ironic and/or jocular, and possibly a combination of -s (“plural marker”) and conflation of -y as adjectival with its sense as a diminutive suffix (e.g., puppy, kitty), the latter notion probably from Scots.

-s pl

1. Used to form regular plurals of nouns that end in certain suffixes or syllables, such as -el, -er, -en, -em, -eur, -aar, -aard, diminutive -je, etc.

   ‎bodem + ‎-s → ‎bodems

   ‎telefoon + ‎-s → ‎telefoons

• Nouns ending in unstressed -e generally have a plural in -s and one in -n (ziekte > ziektes, ziekten). Individual words, however, allow just one of the two ways.
• Most words of Latin origin ending in -um are pluralized with the suffix -s (museum > museums) or by replacing -um with -a (> musea). The latter tends to be preferred in formal style.

2. Used to form adjectives or language names from names of nations or countries.

   ‎Engeland (“England”) + ‎-s → ‎Engels (“English”)

   ‎Finland (“Finland”) + ‎-s → ‎Fins (“Finnish”)

Developed from the use of genitive suffix -s to form adverbial phrases of time or modality modality.

-s

1. Used to form some adverbs

   ‎ander (“other”) + ‎-s → ‎anders (“otherwise”)

   ‎zelf (“self”) + ‎-s → ‎zelfs (“even”)

   ‎maandag (“Monday”) + ‎-s → ‎'s maandags (“on Monday”)

   ‎willend (“wanting”) + ‎-s → ‎willens (“intentionally”)

The adverbial/adjectival -s combines with other suffixes like:

• -lijk → -lijks
• -je → -jes
• -ling → -lings
• -waarts

From earlier forms such as -sz, -se, -sen; all ultimately from the patronymic use of zoon with a connecting genitival interfix -s-. Bare -s as a patronymic may also represent an underlying patronymic use of dochter, as in the name Neeltje Jansdochter, which could reduce to Neeltje Jans by simple elision of -dochter. This etymology is incomplete. You can help Wiktionary by elaborating on the origins of this term.

-s (enclitic particle, somewhat informal or familiar)

1. When appended to a second-person singular or plural imperative, gives the command or request slightly rude or impatient tone—often with different verbs and different independent particles adjacent, the tone is different.

   Kuules nyt! (addressing one person. quite an established expression of frustration, speaker very impatient) ― Now do listen!

   Kuulkaas nyt! (addressing many people, same tone as above) ― Now do listen!

   Tees nämä tehtävät. (addressing one person, tone less impatient) ― Go do these tasks.

2. When appended to the particle -pa/-pä that is appended to a second-person imperative, gives the command or request a slightly more persuasive or inspiring tone.

   Laitapas lautaset pöytään. ― Hey, go put the plates on the table.

3. Mainly in informal contexts: a particle appended to an interrogative suffix -ko/-kö of the verb conjugated in order to bring the conversation partner or a person outside the conversation, talked about, emotionally closer to the speaker, or to create familiarity into the conversation; also to express that closeness or familiarity—sometimes very difficult to translate well into English, in some cases corresponds to tag questions.

   Jaksatkos sinä? ― May you make it maybe?

   Eikös Saara opiskele oikeustieteitä? ― Saara studies law, nuh?

4. (colloquial) appended to the shortened impersonal indicative present form (-n omitted) to soften the command or request or to make it more persuasive.

   Tehdääs tämä huomenna. ― Let's go do this tomorrow.

5. Softens interrogative words, particularly mikä, kuka and their inflected and derived forms, such as when the speaker expects the person addressed to know the answer.

   Mikäs se Suomen pääkaupunki olikaan?

   What was Finland's capital again?

   Kukas heistä olikaan sinun lapsesi?

   Which of them was your child again?

• When attached to imperative forms, the gemination is ignored, unless another enclitic is also used before -s, like with -pas. Thus laitas /lɑi̯tɑs/, but laitapas /lɑi̯tɑpːɑs/.
• When directly attached to forms ending in -n (e.g. passive forms), the -n is often dropped (e.g. miten → mites).

Inherited from Proto-Finnic *-s, from Proto-Finno-Permic *-kse (compare Erzya and Moksha -кс (-ks, nominalizing suffix)).

1. Used to form the regular plurals of most nouns and adjectives.

   ‎homme + ‎-s → ‎hommes

   ‎bon + ‎-s → ‎bons

2. Used to form the irregular plurals of a few nouns and adjectives in -au, -eu (which regularly add -x) and in -al (which regularly make -aux).

   ‎landau + ‎-s → ‎landaus

   ‎bleu + ‎-s → ‎bleus

   ‎carnaval + ‎-s → ‎carnavals

Inherited from Middle French -s, from Old French -s, from Latin -es, -is (second-person singular).

The spread of this suffix to the first-person singular started out from Old French verbs whose stems happened to end in a sibilant, most notably the regular conjugation in -ir, e.g., je fenis, tu fenis (from Vulgar Latin fin-isc-o, fin-isc-is). In later Old French, final /s/ was only pronounced in liaison and in pausa. This weakened the distinction in those verbs which had originally had -s in the second-person only, but by analogy now began to take it in the first-person as well. The grammarians later on standardised the usage, prescribing -s in some cases and rejecting it in others.

• Silent, except in liaison environments, when it may be pronounced /z‿/. This liaison is optional after full vowels (as in tu dois). After silent -e- (as in tu aimes) it is rare and often discouraged.

1. Used to form the second-person singular of most verb conjugations.
2. Used to form the first-person singular of some verb conjugations.

-s

1. used to form the genitive singular of most masculine nouns, neuter nouns, and proper nouns of all genders

The formation of the strong genitive singular (in -s, -es, or no ending) may be of some difficulty both for learners and native speakers.

Only one form is possible in some nouns:

• Nouns in unstressed -as, -es,- is, -os, -us remain unchanged (except those in -nis, which make -nisses).
• Other nouns in -s, -ß, -x, -z take -es.
• Nouns ending in a vowel or in unstressed -el, -em, -en, -er, -or, -um take -s. (Only those in a diphthong or in -h allow -es, alternatively.)
• Nouns forming their plural in -s take the same ending also in the genitive singular. (Apparent exceptions will generally have an alternative plural in -e.)

Otherwise, both forms are usually correct, but certain tendencies can be observed:

• The es-form is strongly preferred in a number of frequently used monosyllables, to the degree that the s-form may even sound odd. No hard rule can be given to identify these nouns; they include e.g. Land, Mann, Weg, etc.
• The es-form is also preferred, for euphonic reasons, in words ending in certain clusters like -pf, -sch, -st.
• Most other monosyllables have no clear preference.
• The s-form is usually preferred in polysyllables, regardless of their being simple or compound and regardless also of stress patterns.

Note, finally, that there is a fairly strong tendency for proper nouns (used with the article) and for newer or less common loanwords to remain unchanged in the genitive singular.

Probably derived from the genitive -s (etymology 1), but developed into a noun-forming suffix in German Low German and Central German dialects.

-s m

1. used to form nouns from verb stems

   ‎klacken + ‎-s → ‎Klacks

   ‎schnappen + ‎-s → ‎Schnaps

Borrowed from Middle Low German . Reinforced by the fact that French and English also use -s as a plural suffix.

• -'s (now proscribed)
• -ens (family names ending with a sibilant consonant)

-s

1. Used to form the plurals of some nouns.
2. Used to form the plurals of personal names, particularly family names.

• The plural ending -s is most typical of loanwords (as in Schals, Parfüms, Videos), though there is a tendency for naturalised loanwords to switch to -e or -en (compare Generäle, Lifte, Pizzen with older Generals, Lifts, Pizzas). Conversely, -s is also used in a certain number of native words (as in Fräuleins, Mädels, Uhus). Moreover, it is the most productive plural marker in contemporary German, typically used to pluralise initialisms (LKWs), neologisms (Honks), and words that do not otherwise have a common plural form (Streits).

-s

1. Used to form adverbs from substantives:

   ‎der Tag (“the day”) + ‎-s → ‎tags (“in the daytime”)

   ‎die Nacht (“the night”) + ‎-s → ‎nachts (“by night”)

   ‎die Linke (“the left”) + ‎-s → ‎links (“on the left”)

   ‎der Anfang (“the beginning”) + ‎-s → ‎anfangs (“initially”)

2. Sometimes used to form adverbs from adjectivess:

   ‎bereit (“ready”) + ‎-s → ‎bereits (“already”)

   ‎beiderrseitig (“reciprocal”) + ‎-s → ‎beiderseits (“reciprocally”)

   ‎hajó (“ship”) + ‎-s → ‎hajós (“sailor”)

3. (number-forming suffix) Added to a cardinal number to form a digit or figure, cf. the relevant template.

   ‎nulla (“zero”) + ‎-s → ‎nullás (“the digit or figure 0”)

4. (frequentative suffix, obsolete) Forms verbs with repetitive meaning. In today's Hungarian language, it is completely obsolete, and its old derivatives are also obscured, e.g. olvas (“to read”), keres (“to seek”), futos (“to run around”).

Inherited from Proto-Indo-European *-s. Cognate with Ancient Greek -ς (-s).

-s

1. suffix marking the nominative singular form of non-neuter nouns and adjectives in declensions other than the first.

The suffix appears most obviously in the third declension, as in urbs. Stem-final consonants are often modified or deleted before the suffix: for example, ‎lēg- (“law”) + ‎-s → ‎lēx (“law”, nominative singular) and ‎dent- (“tooth”) + ‎-s → ‎dēns (“tooth”, nominative singular). Etymologically, the Latin third declension includes both original consonant-stem nouns and i-stem nouns, but these two classes are not consistently distinguished in the nominative singular due to frequent syncope of nominative forms that originally ended in *-is (such as *ǵénh₁tis > gēns), as well as some analogical interchange of endings between these two classes (as in *ḱwṓ and *h₂yéwHō being replaced with canis and iuvenis respectively). The ending -s usually does not appear in the nominative singular of n-stem, r-stem, or l-stem nouns. Most non-neuter n-stems instead drop the -n- and take the ending -ō̆ in the nominative singular (such as homō̆, hominis or carō̆, carnis); a smaller set end in -n in the nominative singular (as in tībīcen, tībīcinis); -s appears only in a handful of irregular formations such as canis, iuvenis, sanguī̆s. R-stem and l-stem nouns (such as āctor, cōnsul) normally have nominative singular forms ending in -r or -l respectively (which are the regular outcomes in Latin of word-final original *-rs and *-ls). Latin nominative singular forms that end in -ns, -rs or -ls are derived by consonant cluster simplification from stems ending in -t- or -d-; e.g. mōns, montis; pars, partis; puls, pultis.

Second declension non-neuter nominative singular forms originally ended in the suffix -s preceded by the Indo-European thematic vowel *-o-. Vowel reduction caused short -o- to be replaced with -u- in closed non-initial syllables, and so Proto-Italic *-os became Classical Latin -us, which is often interpreted as a nominative suffix of its own (an example of rebracketing) rather than a sequence of stem-final vowel + -s. Likewise, in the fourth declension and fifth declension, -s is always preceded by the characteristic vowels of these declensions (-u- and -ē- respectively), with the result that -us and -ēs are frequently regarded as nominative singular suffixes for these declensions.

The suffix -s generally appears only on non-neuter nominative/vocative forms, but it is found in the neuter nominative/vocative/accusative singular of third declension adjectives "of one termination". From an etymological perspective, third-declension neuter nouns such as genus, generis that end in -s in the nominative singular alternating with -r- in oblique forms do not end in this suffix: rather, they are derived from stems that originally ended in the consonant *s (which was changed to -r- by rhotacism when followed by a suffix starting with a vowel).

Inherited from Middle Low German -es, from Old Saxon -es, the masculine and neuter genitive singular ending of strong nouns.

-s vs. -es vs. non-use:

• After l ( , ), -s is used and the l is replaced with i (): pastel → pastéis, capital → capitais,
  • A scattering of exceptions have or allow -es after l, the most common being mal → males
  • After stressed il, -s is used and the l is dropped: hostil → hostis, canil → canis
  • After unstressed il, the ending becomes -eis: réptil → répteis, projétil → projéteis
  • In sporadic and strongly proscribed Brazilian usage, the same rules are applied to words that end in a vowel + u or o (): degrau → * degrais, troféu → * troféis
• After s:
  • -es if the word is stressed in the last syllable: convés → conveses, anis → anises
  • not used otherwise: status → status, íris → íris
• after m, -s is used and the m becomes n; this is an orthographic process, since in both cases the final consonant marks vowel nasalisation: dom → dons
• after n, either, but -es is more common in dialects where it is produced as /n/ rather than vowel nasalisation: hífen → hifens or hífenes
• after r and z, -es is used
• after vowels and semivowels, -s is used
  • the plural of words ending in -ão can be -ões (by far the most common), -ãos (usually masculines with a feminine in -ã) or -ães (only a handful of words)
• loanwords usually follow the same rules: mouse → mouses, ópera → óperas
  • in recent English loanwords ending in r, and occasionally in loans from other languages, -s is used: player → players
  • unadapted loanwords ending in unusual consonants usually take -s or no morpheme: ankh → ankhs, flood → floods, spam → spam or spams
  • rarely, and often alongside a regular form, the plural from the original language is used: campus → campi (also campus), mafioso → mafiosi (more commonly mafiosos), gol → gols (very rarely goles or gois)
  • after x, Hellenisms and Latinisms are usually unchanged (following the rule for words ending in s), but sometimes have -es and the x becomes c (/s/), especially in Brazilian Portuguese: tórax → tórax, clímax → clímax or clímaces
• more often than not, surnames do not take an extra morpheme in the plural; when they do, they are usually Portuguese surnames with recognisable Portuguese morphemes: o Ferreira → os Ferreira or os Ferreiras
• names of peoples that do not contain Portuguese endings usually do not take the plural morpheme: polaco → polacos; ashanti → ashanti or ashantis (less common)

In informal varieties of Brazilian Portuguese, a noun phrase may take a single plural marker, usually in the article. For example, “the big houses” may be as casa grande where standard Portuguese requires as casas grandes. This usage is very widespread, however, it is proscribed and generally regarded as unacceptable in formal contexts and in serious writing.

In some words that end in O and have a stressed /o/ in the penult, the stressed vowel becomes /ɔ/ in the plural. See Category:Portuguese nouns with metaphonic plurals.

Colloquial Brazilian Portuguese allows /j/ to be added before /s/ in words stressed in their final syllables. This is blocked by morpheme boundaries, such that nós (“we”) may be pronounced /nɔjs/, but nós (“knots”) can only be pronounced as /nɔs/. vocês and colloquial forms cês and ocês are an exception to this rule, and can be pronounced /voˈsejs/. Note that this process is usually avoided in formal speech.

• IPA^(key): /s/

Inherited from Old Swedish -s, from Old Norse -s, originally the genitive singular ending of a-stem nouns. Cognate with Danish -s. The frequent use of the suffix in written and modern colloquial Swedish is possibly the result of foreign influence, either Latin or Middle Low German.

   Bilen kör ― The car drives.

   Bilen körs ― The car is (being) driven.

   Bilen körde. ― The car drove.

   Bilen kördes. ― The car was (being) driven.

   Grisen äter. ― The pig eats.

   Grisen äts. ― The pig is (being) eaten.

     Det är en rikedom att få älska och att älskas.

     It is a richness to get to love and to be loved.

2. (chiefly unproductive) Used to form the middle (reflexive and reciprocal) voice of verbs.

   Jag mötte honom. ― I met him.

   Vi möttes. ― We met up. (literally, “We met each other.”)

   Han slog mig. ― He hit me.

   Vi slogs. ― We fought. (literally, “We hit each other.”)

3. (by extension) Used with certain transitive verbs, but without an object, to indicate a habitual or natural action.

   Var försiktig! Hästen sparkas. ― Be careful! The horse kicks .

   Hunden bits. ― The dog bites .

   Han knuffas mycket. ― He pushes people a lot.

• Until the middle of the 20th century, the variant suffix -es was used to mark the present passive of all -er verbs of the second and fourth conjugations. This usage is mostly considered archaic today, but -es is still used for -er verbs whose stems end in s.
• See also vara (“be”), which forms a passive voice for states or completed actions.
• Verbs with the suffix -s that are not passive (including those in 2 and 3 above) are called deponent verbs. In such cases, the passive reading is often also possible. For example, vi slogs might also mean “we were hit” and hunden bits might mean “the dog is bitten”. However, such readings would be unintuitive unless suggested by the context.

Mostly from English -s.
