Pronunciation

Forms

gaga (plural gagas)[1] Daudet's first record (1879) is hyphenated ga-ga.[2]

Etymology

It is an expressive formation imitating the mumbling of old people who have fallen into their second childhood.[2][3][4][5] The Grand Robert and Wiktionary derive it from French gâteux (“senile”), by doubling its first syllable;[6][1] Rey finds the link with that adjective obvious, since it has the same meaning,[3] while the TLFi counts it as only secondary.[2] Bloch and Wartburg note that a syllable ⟨gag-⟩ with the same value is found in other languages.[4][7]

Earliest recorded meaning

Alphonse Daudet first uses it in Les Rois en exil (1879), writing ga-ga of a monarchy left to end its days in an invalid's chair.[2]

Semantic evolution

The word means “in one's dotage, senile”, of a person, usually old, whose mind has failed, and is used as a noun and an adjective.[2][7] By extension it came to mean “idiotic” (1916, Barbusse).[3] Familiar French also says that someone is gaga de a person or thing, “infatuated with”.[8][1]

English took over gaga “crazy, silly” in 1917, as a piece of French slang.[9]

Usage notes

In Saint-Étienne a homograph gaga is a familiar name for the city's people and for the local French of the town and the northern Forez; it comes from Occitan gagas, a nickname of the Stéphanois, and ultimately Latin gagātēs (“jet”), which Wiktionnaire links to the coal deposits on which the town grew.[1][10]
