'non-equine' originates from the prefix 'non-' meaning 'not' and 'equine' from Latin 'equinus', meaning 'of or pertaining to horses'.

'Equine' comes from the Latin word 'equinus', which transformed into the English word 'equine'. The prefix 'non-' was added to form 'non-equine'.

Initially, 'equine' meant 'pertaining to horses', and with the addition of 'non-', it evolved to mean 'not related to horses'.
