The etymology of the term "crocodile bird" can be understood by breaking it down into its components.
- "Crocodile" refers to the reptile known as a crocodile. This word entered the English language in the 16th century from the Middle French word "crocodile", which was derived from the Latin word "crocodīlus". The Latin term, in turn, originated from the Greek word "krokódeilos", where "krokó" means "pebble" and "deilos" means "worm" or "fear". This likely alludes to the appearance and behavior of a crocodile, which resembles a large, scary worm-like creature.
