'rhinoceros-like' is formed in English by combining 'rhinoceros' (from Greek 'rhinokerōs', meaning 'nose-horned') and the suffix '-like', which means 'similar to' or 'resembling'.

'Rhinoceros' comes from the Greek 'rhinokerōs', which became Latin 'rhinoceros', then entered English. The suffix '-like' has been used in English since Old English to form adjectives meaning 'similar to'.

Initially, it meant 'having the qualities or appearance of a rhinoceros', and this meaning has remained unchanged.
