Authors' Note: Reduplications as they are best known, sometimes also called duplications, are language forms (morphs), usually for nouns, in which an element of the word is repeated with little or no change; they figure prominently among the most musical elements in English and in other languages. To this author, the more commonly used term seems redundant. Many other examples begin with the letter 'h', e.g. harum-scarum, helter-skelter, higgeldy-piggeldy, hillbilly, and hubba-hubba.

Authors' Note: (usually, FUD-uhl-dud-uhl, or with a French lilt, as here, fud-uhl-DUD-uhl)
fuddle-duddle: an infrequently used (re)duplication, voiced dismissively in dealing with opinions that the speaker rejects.In 1971 Prime Minister Pierre Trudeau, father of current PM Justin Trudeau, unleashed a minor scandal by using unparliamentary language in the Canadian House of Commons. A portion of the ensuing brouhaha, deftly sidestepped by Trudeau, revolved around whether he had actually spoken or merely mouthed the inappropriate words.Web discussion:https://en.wikipedia.org/wiki/Fuddle_duddle
Authors' Note:
(FUD-ee-dud-ee, or as a possibility here, fud-ee-DUD-ee). Another example of a (re)duplication.
Authors' Note: Higgledy-piggledy is yet another (re)duplication relating to disorder and impetuousness whose meaning overlaps with helter-skelter, and harum-scarum.

Authors' Note:
bubba: stereotyped male inhabitant of the southern US with an upbeat, but macho attitude Bubba: frequent nickname for a specific male, as used by his buddies
