Monster High lexicon

One of the arguable charms of Monster High is its use of puns to monsterfy the language of the characters. Common ways words are monsterfied is by the creation of portmaneaus with the words "claw", "scare", and "creep".

Most of the characters' names themselves are monsterfied puns on regular names and words. In the book continuity, where monsters are discriminated by humans, this is a plot point, as the characters use adjusted versions of their monster names to keep their true identity hidden.
