The apostrophe ( ’ , often rendered as ' ) is a punctuation mark, and sometimes a diacritic mark, in languages that use the Latin alphabet or certain other alphabets. In English, it serves three purposes:

• The marking of the omission of one or more letters (as in the contraction of do not to don't).
• The marking of possessive case (as in the cat's whiskers).
• The marking as plural of written items that are not words established in English orthography (as in P's and Q's, the late 1950's). (This is considered incorrect by some; see . The use of the apostrophe to form plurals of proper words, as in apple's, banana's, etc., is universally considered incorrect.)

Apostrophe (') is an album by Frank Zappa, his eighteenth, released on March 22, 1974 in both stereo and quadraphonic formats. An edited version of its lead-off track, "Don't Eat the Yellow Snow", was Zappa's first chart single, reaching position 86. Apostrophe (') remains Zappa's biggest commercial success in the US. It was certified Gold by the RIAA on April 7, 1976 and reached number 10 on the Billboard Top 200 Albums Chart.
