Etymology
the adverb 'grievously' is built upon the adjective 'grievous', which entered english via anglo-french. its core, the verb 'grever' (to burden, harm), traces back to the latin 'gravāre', meaning 'to make heavy, burden', itself derived from 'gravis' (heavy, serious). the semantic path from physical weight to metaphorical seriousness or severity is clear. the addition of the old english adverbial suffix '-ly' transforms the adjective into a modifier, specifically describing an action performed in a severe, painful, or burdensome manner.
Analysis
grievous (from middle english 'grevous', from anglo-french 'grevous', from 'grever' meaning 'to harm, burden', of latin origin) + ly (from old english '-līce', an adverbial suffix)
