The name of the entry is the term, phrase, symbol, morpheme or other lexical unit being defined.
For languages with two cases of script, the entry name usually begins with a lowercase letter. For example, use work for the English noun and verb, not "Work". Words which begin with a capital letter in running text are exceptions. Typical examples include proper nouns (Paris, Neptune), German nouns (Brot, Straße), and many abbreviations (PC, DIY). If someone tries accessing the entry with incorrect capitalization, the software will try to redirect to the correct page automatically.
For prefixes, suffixes and other morphemes in most languages, place the character "-" where it links with other words: pre-, -ation, -a-, etc.
When multiple capitalizations, punctuation, diacritics, ligatures, scripts and combinations with numbers and other symbols exist, such as pan (as in "frying pan"), Pan (the Greek god), pan- (meaning "all-") and パン (pan) (Japanese for "bread"), use the template {{also}} at the top of the page to cross-link between them. When there are too many variations, place them in a separate appendix page, in this case Appendix:Variations of "pan".
Some variations of the same word kept in multiple pages include:
Some page titles can't be created because of restrictions in the software, usually because they contain certain symbols such as # or |, or are too long. The full list of those entries is at Appendix:Unsupported titles. They are named using the descriptive format "Unsupported titles/Number sign", while using JavaScript to show the correct title like a normal entry.
Matched-pairs, such as brackets and quotation marks, can be defined together as single entries. The entries are named with a space between the left and right characters. Examples: ( ), , “ ”, ‘ ’, " ", „ ”, « », ⌊ ⌋, ¡ ! and ¿ ?.
