IPA: /ˌɛstəˈveɪʃən/
KK: /ɛˈstɪveɪʃən/
A period of dormancy or inactivity that some animals enter during the hot summer months to conserve energy and avoid heat.
Some desert animals go into estivation to survive the extreme heat.
Estivation → It is formed from "aestivus" (meaning summer) and the suffix "-ation" (indicating a process or action). The word "estivation" refers to the process of dormancy or inactivity during the hot summer months, similar to hibernation in winter.
Think of 'summer' ('aestivus') when remembering that 'estivation' means a period of dormancy or inactivity during the hot months.
