An apostrophe is a punctuation that can get used instead of a missing letter or letters in a contraction. It demonstrates either the possession of letters or the lack of letters. For example, the apostrophe serves as a replacement for the letters “w” and “i” in the contraction “we’ll,” which stands for “we will.”
