Morphology

anestrus = estrus (transparent) = an + estrus

Formed by the privative prefix 'an-' (without) plus 'estrus'; if a learner knows 'estrus' the meaning follows directly.

Etymology

The word anestrus comes from the prefix an- meaning 'not' and estrus meaning 'heat', the time when a female animal is ready to mate, so anestrus is the period when the animal is 'not in heat'.
