The evolution of the word is as follows:
* Old French: *gaude* (joy, pleasure)
* Middle English: *gaude* (joy, festivity)
* Modern English: *gaudy* (excessively bright or showy)
The meaning of "gaudy" shifted over time from signifying joy and festivity to describing something excessively bright and showy, likely due to the association of bright colors and extravagant decorations with celebrations and festivals.
