What does tyrant mean?
A tyrant is a ruler who exercises power arbitrarily and oppressively, usually without respecting legal, political, or personal limits. The word may refer to a monarch, dictator, military leader, or other governing figure, but it is rarely used neutrally: describing someone as a tyrant is itself a serious moral and political judgment. In everyday speech, tyrant can also describe a domineering person—such as an overbearing manager, parent, or bully—who controls others through intimidation or unreasonable interference. This figurative sense broadens the word beyond government while preserving its central implication of coercive power. Tyrant is especially forceful because it combines the external fact of unchecked authority with the judgment that such authority is illegitimate or harmful. Its lasting place in English reflects a long history of political conflict over rulers who claimed broad power but governed without restraint.
A ruler who exercises power arbitrarily, especially one whose government is cruel or oppressive; by extension, a person who domineers over others through unreasonable control.
"Fearless journalists exposed the tyrant and helped organize resistance to his rule."
The figurative sense is common in political, social, and workplace contexts.
To act as a tyrant or rule in an arbitrary and oppressive manner.
"The governor tyranted the colony for years, refusing to recognize the local council."
This use is archaic and rare in contemporary English.
The regular plural of the noun; plural is appropriate when referring to multiple oppressive rulers or domineering people.
"The histories describe several tyrants whose reigns ended in rebellion or exile."
A word that can designate both a ruler and the exercise of oppressive power has become one of the clearest symbols of authority used against the powerless.

Where does tyrant come from?
The word entered Middle English in the 14th century from Anglo-French tyrant, a form of Old French tyrant, which came from Latin tyrannus. Latin tyrannus was borrowed from Greek tyrannos, a term used for a ruler or monarch, although the word's earlier Greek history is uncertain. As its use developed, tyrant acquired the strongly unfavorable sense of a ruler who imposes arbitrary or oppressive authority. The same root produced English words including tyranny, tyrannical, tyrannize, and tyrannous.
