'asyngamy' originates from New Latin and Ancient Greek, specifically formed from the Greek prefix 'a-' meaning 'not' plus 'syngamos' (from 'syn-' meaning 'together' and 'gamos' meaning 'marriage' or 'union').

'asyngamy' entered scientific English from New Latin 'asyngamia', which was built on Greek elements related to 'syngamy' (Greek 'syngamia') and came into English usage to describe biological conditions where gamete fusion does not occur.

Initially the components referred generally to 'not-joining' or 'not-marriage'; over time the compound evolved into a technical biological term meaning specifically the 'absence of gamete fusion' in reproduction.
