Many writers become confused because most plural nouns form the possessive by adding only an apostrophe, but children does not follow that rule.

This difference leads to frequent spelling mistakes in schoolwork, business writing, emails, and online content. In this guide, you’ll learn the correct grammar rule, the history behind the word,

British and American English usage, common mistakes, practical examples, comparison tables, FAQs, and tips to remember the correct spelling every time.

Quick Answer

The correct spelling is children’s.

Children’s means belonging to or relating to children.

❌ Childrens’ is incorrect because children is already plural.

Examples

✅ Children’s books are popular worldwide.

✅ The children’s playground is open today.

✅ We visited the children’s museum yesterday.

Quick Rule

Singular noun → add ‘s
Regular plural ending in -s → add ‘
Irregular plural not ending in -s → add ‘s

Since children is an irregular plural, the correct possessive is children’s.

The Origin of Childrens’ or Children’s

The word child comes from Old English cild, meaning a young person.

Its plural became children, which developed during Middle English. Unlike regular nouns that simply add -s, children is an irregular plural, similar to:

man → men
woman → women
person → people
child → children

Because children does not end in s, English grammar requires adding ‘s to show possession.

That is why children’s became the standard possessive form.

The form childrens’ developed from misunderstanding the apostrophe rule. People sometimes think every plural noun only needs an apostrophe after the final s, but that rule applies only to regular plurals ending in s, not irregular plurals.
