The plural of monkey is ‘monkeys’. This is a regular plural form, which means you simply add an ‘s’ to the end of the word to make it plural. For example, if you see one monkey, you would say ‘monkey’, but if you see more than one, you would say ‘monkeys’. This rule applies to most nouns in English, making it easy to remember. So, whether you’re talking about a single monkey or a group of them, you now know the correct way to refer to them.
