Etymology
The word "fad" emerged in the early 19th century, possibly as a shortened form of "fiddle-faddle" (meaning trivial matters) or influenced by French "fadaise" (nonsense). It reflects the fleeting, whimsical nature of trends. Unlike compound words, "fad" resists morpheme division, embodying its own compact history of ephemeral popularity.
