A variant spelling of cormorant, a large waterbird known for diving and fishing; also used to mean a greedy or gluttonous person.
From Old French cormorant, possibly from cor (raven) + morant (dwelling), literally 'sea raven.' The spelling 'corvorant' is an older or dialectal variant of the modern 'cormorant.'
Medieval people thought cormorants looked like ravens that lived on the sea, so they named them 'sea ravens'—the spelling 'corvorant' preserves that old French reasoning before English standardized the spelling.
