"Fuddy-duddy" is considered a word based on
duplication and may have originated as a fused phrase made to form a rhyming jingle. Duddy is similar to Daddy and may have caught on from children's rhyming. Douglas Harper of the
Online Etymology Dictionary reports it from "1871, American English, of uncertain origin." However,
Dictionary.com Unabridged compares it to a Northern English
dialectal term: "1900-05; of obscure origin; compare dial. (
Cumberland)
duddy-fuddiel a ragged fellow." Gary Martin states: "William Dickinson's A glossary of words and phrases pertaining to the dialect of Cumberland, 1899, has: "Duddy fuddiel, a ragged fellow"" and "in 1833, the Scots poet James Ballantyne wrote
The Wee Raggit Laddie: Wee stuffy, stumpy, dumpie laddie, Thou urchin elfin, bare an' duddy, Thy plumpit kite an' cheek sae ruddy, Are fairly baggit, Although the breekums on thy fuddy, Are e'en right raggit." == Application ==
