'arthromeric' originates from Greek, specifically the combining forms 'arthron' and 'meros', where 'arthron' meant 'joint' and 'meros' meant 'part', plus the adjectival suffix '-ic'.

'arthromeric' was formed in modern scientific English by combining the Greek-derived combining forms 'arthro-' (from 'arthron') and '-meric' (from 'meros' via combining form), producing a technical adjective used in anatomical/zoological description.

Initially formed to mean 'pertaining to jointed parts' in technical contexts, the term has retained that specialized meaning and remains primarily used in scientific descriptions of segmented/jointed anatomy.
