'anserid' originates from New Latin (scientific usage), specifically the word 'Anser', where 'anser' meant 'goose' and the suffix '-id' comes from Greek '-idēs' meaning 'belonging to' or 'descendant of'.

'anserid' developed from the Latin word 'anser' (meaning 'goose') into New Latin/modern scientific terms such as 'Anseridae' (the family name), and was adopted into English as 'anserid' to denote members of that group.

Initially it referred directly to the Latin 'anser' meaning 'goose'; over time it came to be used in scientific and English contexts to mean 'a member of the goose-related waterfowl' rather than just a single goose.
