Homonym

A homonym is a word that has more than one meaning. For example, right means moral, the opposite of left, and a personal freedom.

Definition: one of a group of words that share the same spelling and pronunciation but have different meanings.^[1]

The point is that homonyms are both homophones (they sound the same) and homographs (they look the same).
