past tense of hibernate; entered a state of deep sleep or dormancy during winter.
From 'hibernate,' derived from Latin 'hibernare' (to spend the winter); the verb form entered English in the 18th century as scientists needed precise language for animal behavior.
When we say an animal 'hibernated,' we're describing something almost magical—their heart rate drops, their metabolism slows to nearly nothing, and time seems to pause until spring arrives.
