I am a novice in this area so apologies if I use the wrong terminology.

For the purpose of content localization, I am seeking an easy and reliable reference for how numbers map to different plural forms in various languages.

For example, in English 1 (and -1) use singular and all other numbers use plural.

As I understand it, languages like Polish have different rules (ends in 1 but not in 11 uses singular, ends in 2/3/4 but not in 12/13/14 uses plural, all others use genitive plural).

How can one look this up for an arbitrary language?

  • 1 uses singular and all others plural? What does that mean? Ok, so, it depends on the use in context.

I found https://www.unicode.org/cldr/charts/43/supplemental/language_plural_rules.html, which seems like a perfect resource.

    Just remember that knowing which number and case of a noun to use with which numeral isn’t necessarily enough; in many cases, the noun itself also matter. For example, in Chinese, the noun and the context determines which measure word to use (e.g., when counting 人 [people] in a general context, you’d count 一/两/三, but if it’s the number of people for a booking, it would be 一/两/三); or in Irish, both the number (singular/plural) and the initial mutation depends on the noun (e.g., cat vs ceann vs bróg: 2 chat/cheann/bhróig, 3–6 chat/cinn/bhróg, 7–10 gcat/gcinn/mbróg.

    Plus suppletion comes into it as well. Consider Russian 1 год, 2 года, 5 лет. The form годов does not occur with numerals as you would expect from many other nouns. Feb 23 at 15:40
  • @OmarandLorraine Or even English: 1 person, 2 people. Feb 24 at 18:08
