The loud, distinctive call or crow that a rooster makes, especially in the early morning.
An onomatopoeia—a word that imitates the sound it describes. The 'cock-a-doodle-doo' attempts to capture the actual noise a rooster makes, and this imitative word has been used since at least the 16th century.
Different languages hear this same rooster cry completely differently—in French it's 'cocorico,' in Spanish 'quiquiriquí,' and in Japanese 'kokekokko.' It's wild how the same animal sound gets filtered through our linguistic brains in totally different ways.
