CATAPOSTROPHE

The misuse of the apostrophe, esp. where such misuse results in an amusing or ambiguous sentence. Example: In a recent advertisement for a freezer, the company used the term its' cool box. This catapostrophe meant that it was not clear whether the box is cool, or whether the freezer has a cool box. The words its' of course, does not exist. [See prior entry at it's.]
