the word ungainly is a negative formation from the now-obsolete adjective 'gainly', which meant graceful or suitable. 'gainly' itself derives from the old norse word 'gagn', signifying advantage or straightness, which entered middle english as 'gayn'. the prefix 'un-', of germanic origin, is added to reverse the meaning. thus, the literal construction "not graceful" directly conveys the modern sense of being awkward or clumsy, illustrating how a simple negation preserved a root that has otherwise faded from common use.

Structure: un (not) + gainly (graceful) un- (old english, a prefix meaning "not"); gainly (obsolete english, from old norse 'gagn', meaning "straight, suitable, graceful").
