trick
The French word 'piège' translates to 'trick' in English. It is often used to describe a deceptive or cunning plan or action, similar to the English usage. However, it can also refer to a trap or snare, which is not always the case with the English word 'trick'. Therefore, context is important when using this term.

This sentence could be used literally, if Tom physically fell into a trap, or metaphorically, if Tom fell for a deceit or trick.

This phrase is often used to warn someone of a potential danger or trick. It is a common phrase in both conversational and written French.
I avoided the trap.
This phrase can be used literally if the speaker avoided a physical trap, or metaphorically if they avoided a trick or potentially dangerous situation.
