Usage Note
Serpent is the standard word for snake; the final t is silent. In figurative use serpent can mean a treacherous or deceitful person, echoing the biblical serpent. The phrase un serpent dans l'herbe ('a snake in the grass') carries the same idiomatic meaning as in English. A smaller snake is sometimes called une couleuvre.
Examples
"Un serpent traversait le chemin."
