'amphipod-like' originates from English, specifically the noun 'amphipod' combined with the suffix '-like', where 'amphi-' (from Greek) meant 'both' and 'pod' (from Greek 'pous') meant 'foot'.

'amphipod' comes from New Latin 'Amphipoda' (the taxonomic name), itself from Greek elements 'amphi-' + 'pous' ('amphi-' = 'on both sides' / 'around', 'pous' = 'foot'); the English suffix '-like' derives from Old English 'lic' meaning 'having the form of', and these elements were combined in modern English to form 'amphipod-like'.

Initially the Greek roots conveyed 'both/around' + 'foot' to name the crustacean group; over time the compound name 'amphipod' came to denote the specific small crustaceans, and adding '-like' yielded the current adjectival meaning 'resembling an amphipod'.
