Etymology

It is inherited from Middle English uncle, borrowed from Anglo-Norman uncle and Old French oncle,[2][3][4] from Late Latin aunculus, from Latin avunculus (“mother's brother”),[3][5] literally “little grandfather”, a diminutive of avus “grandfather”,[6][2] from Proto-Indo-European *awo- (“grandfather, adult male relative other than one's father”).[6][2] Latin had patruus for a father's brother.[6] It replaced Old English ēam, mostly “mother's brother”, the Germanic form of the same root, which survives in Dutch oom.[6][2][4] It is related to avuncular.[7]

Earliest recorded meaning

The brother of one's father or mother: about 1290 in the OED, about 1300 in Etymonline and Barnhart.[8][6][2] It is found as a surname from the late 12th century.[6]

Semantic evolution

As a title before a name it is from the mid-15th century.[6] From the late 16th century, an uncle was sometimes taken as a nuncle, and Shakespeare's Fool calls Lear “nuncle”.[7] The slang sense “pawnbroker” is by 1756.[6] As a familiar form of address to an older man it is by 1793.[6][8] Dutch uncle is from 1838,[8] and Uncle Sam, for the United States government, from the early 19th century.[7] In BBC radio, uncle was a male announcer of children's programmes from 1923,[8] and a mother's male friend or lover from 1962.[8]
