Apostrophe
punctuation mark and diacritic mark / From Wikipedia, the free encyclopedia
The apostrophe is a punctuation mark used in writing. It is a diacritic (a mark used with letters).
In English, it has two jobs:[1]
- To show where one or more letters have been left out, as in the abbreviation (contraction) of do not to don't.
- To show the possessive case, as in the cat’s whiskers.
