Treacherous is an adjective.

Word history: The word treacherous comes from the Middle English trecherous, which evolved from the Old French trecheros.

Here’s a sentence that combines both meanings: The treacherous mountain pass was made even more dangerous by the treacherous guide who abandoned the hikers midway.
Common errors in use: One common error when using treacherous is confusing it with treasonous. While both words involve betrayal, treasonous specifically refers to betrayal against one’s country or government.
Treacherous is broader and can apply to any type of betrayal or hidden danger. Another mistake is using treacherous to describe a person or thing that is merely difficult or challenging, but not actually deceitful or dangerous.
