English plural forms tend to be pretty simple, in most cases. You usually add s/es/ies in the end of the word and your job is done.

Examples:

kid -> kids

box -> boxes

baby -> babies

However, some words change differently.

Examples:

child -> children

man -> men

woman -> women

person -> people

mouse -> mice

foot -> feet

fish -> fish

sheep -> sheep

datum -> data

bacterium -> bacteria

How can you know the plural form of each word? You can always check it in the dictionary.
