conjoined

The word 'conjoined' is built upon the Latin verb 'coniungere', which itself is a compound of the intensive prefix 'con-' (together) and 'iungere' (to join). 'Iungere' traces back to the Proto-Indo-European root yeug-, meaning 'to yoke' or 'to harness', a concept central to joining animals or objects. As the term passed through Old French ('conjoindre') and into Middle English, its application broadened from physical linkage to any form of union. The modern adjective 'conjoined', formed by adding the participial suffix '-ed' to the verb 'conjoin', specifically denotes a state of being united, most famously applied in biology to describe twins physically connected from birth.
