Pronunciation

Forms

dauphin m (plural dauphins)[1] Old French daufin, later remade as dauphin after the Classical Latin form.[2][3] As a title, Dalfin (1245) and dalphin, then doffin (1410) and dauphin (1420).[4]

Etymology

It is inherited from Old French daufin, inherited from Vulgar Latin *dalphinus (recorded in 710), an altered form of Classical delphīnus (“dolphin”), which is from Ancient Greek δελφίς (delphís, “dolphin”).[2][5][4] Bloch and Wartburg and the GLLF take the French word as borrowed from Old Occitan dalfin; the TLFi finds that unnecessary.[6][7][2] Rey connects the Greek word with δέλφαξ (délphax, “young sow”), as if the animal were the “piglet” of the sea.[4]

The title comes from a personal name: Late Latin Delphinus (4th century), Dalphinus (5th century), borne by a bishop of Bordeaux, became the surname of the lords of the Dauphiné (1110–1140) and of Auvergne (1167), then a title, and gave the province its name.[4][3] According to Rey the dolphin in the arms of these lords is a play on their name, not its origin;[4] Wiktionary and Etymonline instead derive the title from the dolphin of their arms.[1][8]

Cognate with Italian delfino, Spanish delfín and Portuguese delfim.[9]

Earliest recorded meaning

It is first found as daufin in a manuscript of the Roman d'Alexandre (mid-12th century), naming the dolphin.[2][4]

Semantic evolution

Besides the animal, the word names things shaped like it: the spout of a fountain, the curved end of a downpipe, and a constellation recorded by the Académie in 1835.[2][10]

As a title it was borne by the lords of the counties of Albon and Viennois, whose lands were called the Dauphiné; it is a title in Auvergne from 1281 and in the Dauphiné from 1282.[4] After the Dauphiné passed to the French crown in 1349, the title dauphin de Viennois (1360) was given to the eldest son of the king.[4][2] Dauphin alone has named the heir to the throne since 1420.[4][2][3] The feminine daufine (1297) named the dauphin's wife.[4]

Under Louis XIV it was used figuratively of the only son of a family, or of anyone much pampered (1690),[4][11] and today it names the expected successor of an important person in politics or business (1941).[4][2] English took the title in the early 15th century.[8]
