Etymology

From Middle English delphyn, from Latin delphīnus, from Ancient Greek δελφίς (delphís), from δελφύς (delphús, “womb”); the modern form in -ol- is probably influenced by the pronunciation of Middle French dauphin. Compare Swedish delfin. Doublet of dauphin. Displaced native Old English mereswīn (literally “sea pig”), whence English mereswine.
