Naming things

Naming things is hard.

"'There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors.' – Phil Karlton"

General advice

 * Avoid ambiguity :Search for similar keywords in existing features, extensions, products, and projects, to avoid confusion and a profusion of hatnotes and seealsos. (e.g., Collection vs Collections, Labs vs labs vs labs, Page Previews vs page previews)
 * Make it easy to pronounce, to type, and to remember :Avoid l33t5p34k, avoid difficult capitalizations (e.g., SyntaxHighlight GeSHi), and don't use dashes if CamelCase is the local convention.
 * Consider the translations :If it is a user-facing feature, this is extra important. Is the word almost-untranslatable or extra-long, in any discoverable language? (e.g., help, randompage, BetaFeatures (T58537), [better examples needed...] ) Metaphors and idioms may have different meanings in other languages or cultures.
 * Check it isn't a reserved keyword in the usual programming languages :This can lead to additional complexity in the code (e.g., Echo). For example: Puppet reserved words.
 * Abbreviations :For long names, specify the short form. People tend to shorten anything they can, especially if they write it regularly, as help-desk people and developers tend to do. Contractions/Initialisms/Acronyms will be invented, if you don't plan for it. (e.g., visual editor is "VE" to many people, see also Glossary and Manual:Glossary)
 * Stick with a single name :Try to pick just one name, for both the code & the user-facing product name. Otherwise you'll have to regularly explain the past/alternative names, and deal with persistent confusion. (e.g., Page-triage/Page-curation/Newpagepatrol/Newpagesfeed, or Echo/Notifications, or Popups/Hovercards/PagePreviews). Renaming things is even harder: the first name used in public is likely to stick, even if you think it's terrible.
 * Use inclusive language
