Etymology
Etymology Information

'extracosmic' originates from Latin, specifically the prefix word 'extra', where 'extra' meant 'outside' or 'beyond', combined with 'cosmic' ultimately from Greek 'kosmos' meaning 'order' or 'world'.

Historical Evolution

'extracosmic' was formed in modern English by combining the Latin prefix 'extra' + the adjective 'cosmic' (from New Latin/Greek roots); this compound construction ('extra-cosmic') eventually stabilized as the single-word adjective 'extracosmic'.

Meaning Changes

Initially the components separately meant 'outside' (extra) and 'world/order' (kosmos); over time the compound came to be used specifically to mean 'outside or beyond the known universe' or 'beyond the ordered cosmos'.
