What does ambush mean?
An ambush is a surprise attack carried out by people who have concealed themselves and waited quietly for their target to pass. As a noun, it names both the attack itself and the hidden position from which it is launched; as a verb, it describes the act of lying in wait to strike unexpectedly. The word is deeply associated with military history — from forest warfare to modern guerrilla tactics — where attacking from concealment offers a decisive advantage over a stronger force. Beyond the battlefield, ambush is often used figuratively: a journalist might be said to have ambushed an official with unexpected questions, or a friend to have been ambushed by a surprise party. The word carries connotations of stealth, patience, and sometimes treachery, since the victim typically has no chance to prepare or defend themselves. Its etymology reflects its meaning: it derives ultimately from a Latin expression meaning 'in the wood', capturing the image of attackers hidden among trees.
A surprise attack by people lying concealed and in wait; also, the hidden position from which such an attack is made.
"The convoy was caught in an ambush on the mountain road."
To hide in a concealed position in order to make a sudden, unexpected attack on someone.
"They ambushed the patrol as it crossed the river."
Often used with objects: 'they ambushed the convoy'.
The word traces back to a Latin phrase meaning literally 'in the wood' — ambush was born from the idea of hiding among the trees.

Etymology of ambush
Ambush entered English in the 16th century from Middle French, where the term was embusche (modern French embuscade). The French word itself derives from a Late Latin or Romance expression meaning 'in the wood' (Latin imboscata, literally 'in bosco'), reflecting the tactic of concealing troops in forests. Related historical English forms include the now-archaic embushment and the borrowed embuscade.
