Etymology
Origin of ambush
1250–1300; (v.) Middle English enbuss ( h ) en < Middle French embuschier to place men in ambush, literally, to set in the woods, equivalent to em- im- 1 + busch- (< Vulgar Latin *busca wood, forest < Germanic *busk- heavy stick) + -ier infinitive suffix; (noun) earlier enbusshe < Middle French embusche, derivative of the v.
Explanation
An ambush is a sneak attack. To ambush your enemy, hide and wait for him to come near and then pounce on him. In war or in backyards, an ambush is a great way to surprise someone. Ambush comes from a Latin word meaning “to place in a wood,” and hiding in the woods behind a tree is a classic starting point for an ambush. The actual attack is called an ambush, but ambush is also a verb, so you can ambush your mom by dropping water balloons on her head from a tree. Please don’t tell her where you got that idea.
