Editing for Grammarphobes: Plurals

The plurals of most nouns are formed by adding an s. When the noun ends in a soft ch or in s, sh, j, x, or z, however, add an es.


If the noun ends with a y preceded by a consonant, the plural is formed by replacing the y with ies.

Most compound nouns that are written as one word take the plural in the usual way. But, hyphenated and open compounds are made plural by adding the s to the element that is subject to change in number.
