'alectoromorphous' originates from Greek, specifically the word 'alektoromorphos,' where 'alektor' meant 'rooster' and 'morphos' meant 'form or shape.'

'alektoromorphos' transformed into the English word 'alectoromorphous' through the adaptation of Greek roots into English.

Initially, it meant 'having the form of a rooster,' and this meaning has largely remained the same in modern usage.
