'Aradidae' originates from New Latin (taxonomic), specifically from the genus name 'Aradus' combined with the suffix '-idae', where '-idae' indicates a family (from Greek '-idēs' via Latin).

'Aradidae' was formed by adding the standard zoological family suffix '-idae' to the genus name 'Aradus' (a genus established in modern entomology in the 19th century), producing the family name used in taxonomic literature.

Initially used as a formal taxonomic label derived from 'Aradus'; over time this has remained essentially the same — a family-level taxon of flat bugs.
