Etymology
the word 'fatigued' entered english in the 17th century from the french verb 'fatiguer', meaning 'to tire'. the french term itself was borrowed from the latin 'fatigare', a verb signifying 'to weary' or 'to tire out'. the ultimate origin is uncertain but may be connected to a proto-indo-european root meaning 'to cause to break' or 'to be weary', a semantic link that persists in the modern sense of being worn out or exhausted. the '-ed' suffix marks its adjectival use as a past participle, describing a state of having been tired.
