👉 Apostrophes are punctuation marks used to indicate emphasis, a pause or a change in word order. They can be placed at the beginning of sentences or phrases to separate them from other elements in a paragraph or text. For example: - "She said, 'I love you.'" - "He looked at her, and then walked away." Apostrophes are often used to indicate emphasis or to suggest a pause or change in word order within a sentence.
