Word Origin & Etymology

First recorded in the mid-16th century, the adjective derives from 'cock' (a rooster) plus the suffix '-y', alluding to the bold, strutting, and pugnacious behavior of a barnyard rooster. The Australian and New Zealand noun senses arose independently in the 19th century as a colloquial shortening of 'cockatoo' (applied metaphorically to small-scale farmers who picked over small plots of land like a flock of cockatoos).
