dolphin
UK: ˈdɒlfɪn | US: ˈdɑːlfɪn
n. A highly intelligent marine mammal with a streamlined body, a beak-like snout, and a dorsal fin, belonging to the family Delphinidae.
The word "dolphin" traces back to the Greek delphis (genitive delphinos), meaning "dolphin" or "womb," possibly due to the animal's resemblance to a fish with a rounded belly. The Latin delphinus later adopted the term, which evolved into Old French dauphin and Middle English dolfin. The modern spelling stabilized in the 16th century. The Greek root reflects the creature's ancient cultural significance, often associated with Poseidon in mythology.
