threat: [OE] Threat originally meant ‘trouble, oppression’; ‘expression of an intention to do harm’ is a secondary sense, which arose out of the notion of ‘putting pressure’ on someone. It came from a prehistoric base *thraut-, *threut-, *thrut-, which probably went back to Indo- European *trud- ‘push, press’ (source also of Latin trūdere ‘thrust’, from which English gets abstruse, intrude, etc, and probably also of English thrust). => abstruse, intrude
threat (n.)
Old English treat "crowd, troop," also "oppression, coercion, menace," related to treotan "to trouble, weary," from Proto-Germanic *thrautam (cognates: Dutch verdrieten, German verdrie?en "to vex"), from PIE *treud- "to push, press squeeze" (cognates: Latin trudere "to press, thrust," Old Church Slavonic trudu "oppression," Middle Irish trott "quarrel, conflict," Middle Welsh cythrud "torture, torment, afflict"). Sense of "conditional declaration of hostile intention" was in Old English.
