Learning
Memory Aids

Conceptual Metaphor
TYRANNY IS A DISEASE, TYRANNICIDE IS SURGERY / THE TYRANT IS A BEAST, TYRANNICIDE IS HUNTING
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'тиранид' (a type of rock).
- The suffix '-cide' is more specific than the general Russian 'убийство'. It denotes a specific *class* of killing.
Common Mistakes
- Using it to mean 'killing by a tyrant' (the reverse meaning). Correct: 'Brutus committed tyrannicide against Caesar.' Incorrect: 'Caesar's tyrannicide killed many citizens.'
- Using it as a general term for any assassination.

Regicide is the killing of a king or queen, regardless of their behaviour. Tyrannicide is the killing of a tyrant (an oppressive ruler), who may or may not be a monarch. A king could be both regicided and tyrannicided if he was a tyrant.
It can be, but it's very rare and carries heavy historical and formal weight. It would typically be used in analytical or rhetorical contexts, not in news reports about modern assassinations, where 'assassination' is the neutral term.
