• (modern Italianate Ecclesiastical) IPA^(key): /ˈsa.t͡ʃer/,

sacer (feminine sacra, neuter sacrum, superlative sacerrimus); first/second-declension adjective (nominative masculine singular in -er)

1. sacred, holy, dedicated (to a divinity), consecrated, hallowed (translating Greek ἱερός)
   • c. 200 BCE, Plautus, Menaechmi V.5.38:

     at ego te sacram coronam surrupuisse Iovi scio

     And I know that you stole the sacred crown of Jupiter.

2. devoted (to a divinity for sacrifice), fated (to destruction), forfeited, accursed
   • 29 BCE – 19 BCE, Virgil, Aeneid III.56:

     quid non mortalia pectora cogis / auri sacra fames

     Accursed hunger for gold, what do you not compel the hearts of men to do!

3. divine, celestial
   • 29 BCE – 19 BCE, Virgil, Aeneid VIII.591:

     extulit os sacrum caelo tenebrasque resoluit

     lifts to the skies his countenance divine, and melts the shadows of the night away.

   • early 7th c. CE, Isidore of Seville, Etymologiae sive Origines 9.1:

     Tres sunt autem linguae sacrae: Hebraea, Graeca, Latina, quae toto orbe maxime excellunt.

     Three are the sacred languages: Hebrew, Greek and Latin, all of which distinguish themselves in the whole world.

     ego sum malus ego sum sacer scelestus

     I am a bad one, I am a cursed one—a wicked one.

The comparative form *sacrior and its inflected variants are not attested, even though the superlative sacerrimus is attested.

First/second-declension adjective (nominative masculine singular in -er).

• (accursed): scelestus
• (consecrated, sacred): augustus, sānctus
• (detestable): exsecrābilis, scelestus

• (antonym(s) of “holy”): dēfānātus

From Proto-Italic *sākris (“sacrificial, sacred”), from Proto-Indo-European *seh₂k- (“to sanctify, to make a treaty”).

• (Classical Latin) IPA^(key): /ˈsaː.ker/,
• (modern Italianate Ecclesiastical) IPA^(key): /ˈsa.t͡ʃer/,

Generally cited with a long vowel by etymological sources. Per Nishimura (2014), citing Timpanaro (1965), the only evidence of the long vowel in the first syllable is the scansion in Plautus's Rudens (below). Syllables containing short vowels before a plosive-liquid cluster such as /kr/ are not usually treated as heavy in Plautine poetry.^[1]

sācer (feminine sācris, neuter sācre); third-declension three-termination adjective (uncommon)

     responde mihi / adulescens: quibus hic pretiis porci veneunt / sacres sinceri?

   • c. 211 BCE, Plautus, Rudens 1208:

     sunt domi agni et porci sacres.

Third-declension three-termination adjective.
