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.

noun

  1. 1

    A man-made semi submerged maritime structure, usually installed to provide a fixed structure for temporary mooring, to prevent ships from drifting to shallow water or to serve as base for navigational aids.

Etymology

Ultimately from 3rd Duke of Alba (duc-d'Albe in French), who was the first to build this type of structure in the Spanish Netherlands in the 16th century. Possibly from Dutch dukdalf, or the plural dukdalven, through elision of the initial duk-.
