Set a trap

[poli]

I know trampa and zancadilla, but honestly the only way I could think of setting one is utilizer una tramp/zancadilla. I imagine there is a better way.

[aleCcowaN]

tender una trampa is a collocation used in dubbing

here, it would be poner una trampa

if you are talking about -figuratively or not- setting a trap like those with iron teeth to catch game or a ruse to entrap somebody.

[AngelicaDeAlquezar]

A "trampa" is like one of those to catch wild animals. Figuratively, it's a situation to make someone a victim of some kind of abuse or crime, or to make them look as guilty of something.

"Poner una zancadilla" is to trip someone up.
