A member of the marsupial family Didelphidae, particularly opossums and related species; or as an adjective, relating to this family.
From 'Didelphis' (the genus) plus the suffix '-id,' used in taxonomy to create family member nouns and adjectives.
The suffix '-id' in taxonomy creates a personal-sounding noun—a didelphid is like a 'member of the didelph club'—making it easier to talk about family relationships in nature by turning Latin categories into countable beings!
