What makes someone a tyrant?

A glance at the comments posted in response to our definition of tyrant illustrate two things: the word has a fairly wide spectrum of meaning, and many political rulers of late (regardless of party and action) are thought by some to merit this description. The word is often now found used as a generalized term of reproach ("he was a real tyrant in the kitchen"), and also with more specific denotation ("the tyrant suspended the country’s judicial code"). The definitions we give for words match, as best as possible, the manner in which these words are used. We cannot offer judgment on whether or not any specific individual is or is not a tyrant.
