==Formation of plurals==
A given language may make plural forms of nouns by various types of [[inflection]], including the addition of [[affix]]es, like the English ''-(e)s'' and ''-ies'' [[suffixes]], or [[ablaut]], as in the derivation of the plural ''geese'' from ''goose'', or a combination of the two. Some languages may also form plurals by [[reduplication]], but  not as productively. It may be that some nouns are not marked for plural at all, like ''sheep'' and ''series'' in English. In languages which also have a [[grammatical case|case]] system, such as [[Latin]] and [[Russian language|Russian]], nouns can have not just one plural form but several, corresponding to the various cases.  The inflection might affect multiple words, not just the noun; the noun itself need not become plural as such, with other parts of the expression indicating the plurality.

In English, the most common formation of plural nouns is by adding an ''-'''s''''' suffix to the singular noun. (For details and different cases, see [[English plurals]].) Just like in English, noun plurals in French, Spanish, and Portuguese are also typically formed by adding an ''-s'' suffix to the lemma form, sometimes combining it with an additional vowel. (In French, however, this plural suffix is often not pronounced.) This construction is also found in German and Dutch, but only in some nouns. Suffixing is cross-linguistically the most common method of forming plurals.

In [[Welsh language|Welsh]], the reference form, or default quantity, of some nouns is plural, and the singular form is formed from it, e.g., ''llygod'', mice -> ''llygoden'', mouse; ''erfin'', turnips -> ''erfinen'', turnip.
