And one to two sentences, explain how to use an apostrophe to show a possession for singular or plural nouns and to form contractions

Answer 1

To show possession for a singular noun, add an apostrophe followed by an "s" (e.g. The cat's tail). For plural nouns ending in "s," only an apostrophe is added after the "s" (e.g. The dogs' toys). To form contractions, use an apostrophe to replace missing letters and combine words (e.g. can't for cannot).
