"Flatette" is a relatively modern word that originated in the early 20th century. Unfortunately, there is limited information available on its etymology. It seems to be a blend of the words "flat" and the diminutive suffix "-ette". "Flat" refers to an apartment or dwelling with multiple rooms on a single level, while "-ette" is often used to create a diminutive form of a word, indicating something small or of lesser size. The combination of these elements likely gave rise to the term "flatette", suggesting a small or compact apartment or dwelling space. However, due to the lack of extensive historical sources on this term, its exact origin and development remain somewhat unclear.
