LowFormal/Technical/Scientific
Definition
Meaning
A state of animal dormancy or torpor during a hot or dry period, analogous to hibernation but in summer.
In botany, the arrangement of flower petals within a bud before it opens; in zoology, the summer dormancy of certain animals to survive arid conditions.
Linguistics
Semantic Notes
The primary modern meaning is the zoological one (summer dormancy). The botanical meaning (bud arrangement) is more specialised and less common in general discourse.
Dialectal Variation
British vs American Usage
Differences

Connotations
Identical in both variants — strictly technical/scientific.
Frequency
Extremely low frequency in everyday language in both variants, but the spelling follows regional conventions.

Frequently Asked Questions
Aestivation is summer dormancy to avoid heat and aridity; hibernation is winter dormancy to avoid cold and food scarcity.
In British English: /ˌiːstɪˈveɪʃ(ə)n/ (eest-iv-AY-shun). In American English (as 'estivation'): /ˌɛstɪˈveɪʃ(ə)n/ (est-iv-AY-shun).
No. It is a specialised scientific term. The average person is unlikely to encounter or use it.
In a strict zoological sense, no. But plants can enter dormancy during drought. The related botanical term 'aestivation' refers only to bud structure, not dormancy.
