means Someone who murders a specific, usually prominent, target for political, ideological, or paid reasons, as a calculated act rather than a crime of passion.

from Traces back to 'hashshashin,' tied to a real medieval sect in Persia and Syria — the Nizari Ismailis — who carried out targeted killings of political and religious enemies. European chroniclers, especially Crusaders, picked up the Arabic term and linked it to 'hashish,' spreading tales that the killers were drugged into fearless devotion before their missions. Most historians now treat that drug-fueled origin story as more legend than fact — likely propaganda or misunderstanding by outsiders — but the name stuck, and by the time it entered European languages it had hardened into a general word for a hired or ideological killer.
