Etymology

unsuitable = un<not> + suit<fit> + able<capable of>

  • un: A prefix of negation, from Old English "un-," meaning "not."
  • suit: From Old French "suite," meaning "a following" or "fit," derived from Latin "sequi" (to follow). Evolved to mean "appropriate" or "compatible."
  • able: A suffix from Latin "-abilis," indicating capability or suitability.

Etymology Origin:
The word "unsuitable" combines the negative prefix "un-" with "suit," which originally referred to a sequence or agreement (from Latin "sequi"). Over time, "suit" evolved to mean "fitting" or "appropriate," and the suffix "-able" was added to form an adjective. Thus, "unsuitable" literally means "not capable of fitting" or "inappropriate."
