lacking an amnion

Etymology
Etymology Information

'non-amniote' originates from English, formed by the negative prefix 'non-' (from Latin 'non', meaning 'not') attached to 'amniote', which comes via New Latin 'Amniota' from Greek 'amnios' meaning 'a lamb's membrane' or 'fetal membrane'.

Historical Evolution

'amniote' came into English from New Latin 'Amniota', ultimately from Greek 'amnios'; the combining form 'non-' was added in English to create the compound 'non-amniote', used to denote organisms lacking an amnion.

Meaning Changes

Initially, 'amniote' designated animals with an amnion; adding 'non-' produced 'non-amniote' to mean 'not having an amnion' or 'belonging to animals without an amnion'.
