'andrenid' originates from New Latin, specifically the word 'Andrena,' which is the type genus of the family Andrenidae, with the suffix '-id' denoting a member of a family in zoological taxonomy.

'Andrena' (the genus name) was used in scientific classification, and the suffix '-id' was added to form 'andrenid,' referring to members of this bee family.

Initially, it referred specifically to members of the genus 'Andrena,' but over time it came to refer to any member of the family Andrenidae.
