'unhurlable' originates from the prefix 'un-' meaning 'not' and the verb 'hurl', which comes from Middle English 'hurle', meaning 'to throw with force'.

'hurle' transformed into the modern English word 'hurl', and with the addition of the prefix 'un-' and the suffix '-able', it became 'unhurlable'.

Initially, 'hurl' meant 'to throw with force', and 'unhurlable' evolved to mean 'not capable of being thrown'.
