Singular and Plural FAQs
What is the plural of child?
The plural of child is children. It is irregular, so we never say “childs.” Example: One child is singing. Three children are singing.
What is the plural of sheep?
Sheep stays the same: one sheep, ten sheep. Deer, fish, aircraft and species work the same way. Use the verb to show the number: The sheep is here. The sheep are here.
Is data singular or plural?
Data is the plural of datum in formal and scientific writing: The data are clear. In everyday English, most people treat data as a singular mass noun: The data is clear. Both are widely accepted, but pick one style and stay consistent.
What is the plural of octopus?
The safest and most common plural is octopuses. You may also see octopodes. The popular form octopi is common too, but it is based on a Latin pattern that octopus, a Greek word, does not really follow.
Why do some nouns not change in the plural?
Many animal names, such as sheep, deer and fish, come from old English counting habits, and the zero plural simply survived. Words like series and species come from Latin forms that already ended in -s, so English kept them unchanged.
What is the difference between a regular and an irregular plural?
A regular plural is built with a spelling rule, usually by adding -s or -es (dog – dogs, watch – watches). An irregular plural changes in some other way, or not at all (man – men, mouse – mice, sheep – sheep), so irregular plurals have to be memorized.
