'horse' originates from Old English, specifically the word 'hors', where a Proto-Germanic root (reconstructed as '*hursa-' or similar) referred to a hoofed animal.

'horse' changed from Proto-Germanic roots into Old English 'hors' and eventually became the modern English word 'horse'.

Initially, it referred to a hooved domesticated animal used for riding and work; over time the basic meaning has remained largely the same, though many cultural associations (e.g., sport, transport, idioms) have developed.
