Etymology: "Pelecaniform" is a technical coinage built from two parts: the Greek-derived "pelekan," meaning "pelican" (from Greek "pelekan," itself linked to the verb "pelekan," to hew or chop, a reference to the bird's broad bill), and the Latin suffix "-formis," meaning "having the form or shape of." Taken together, the word literally means "pelican-shaped" or "pelican-like." The term was coined by scientists classifying birds, not by the ancient Greeks or Romans, who had no concept of this grouping. Ornithologists in the 19th and early 20th centuries used "-iform" suffixes to name orders by a representative member, following the same pattern as "passeriform" (perching birds, after the sparrow family's Latin name "passer") and "anseriform" (after "anser," goose). The pelican-based name was chosen to label a group that shares the pelican's characteristic features, even though the order includes birds that look quite different from pelicans, such as herons and ibises.
