fatiguing

the word 'fatiguing' originates from the latin verb 'fatigare', meaning to tire out or weary. this latin root itself is of uncertain origin, though it may be connected to an older indo-european sense of striking or pressing down, metaphorically extending to the burden of exhaustion. entering english via french 'fatiguer', the verb 'fatigue' was formed, and the present participle suffix '-ing' was added according to standard english grammatical patterns to create the adjective. thus, the literal construction "causing to tire" directly and logically yields the modern meaning of something that induces weariness.

Structure: fatig (weariness) + u (connective) + ing (adjective suffix) fatig (from latin 'fatigare', meaning to tire out, to weary); u (a common connective vowel used in english word formation); ing (a suffix forming present participles and adjectives from verbs, from old english '-ende' and '-ing').
