Apostrophes Grammar Skill

Apostrophes are punctuation marks used to show possession or to form contractions. They help clarify meaning by showing ownership or indicating missing letters in words.

For example, in the sentence “The dog’s leash is missing,” the apostrophe shows possession. In “I can’t find my keys,” the apostrophe replaces missing letters in the contraction can’t.

Apostrophes are often confusing for students because they look similar to plural forms. Learning when to use apostrophes correctly helps writers avoid common grammar mistakes.

Students typically learn apostrophes alongside plurals and contractions as they develop their writing skills.
