frustratingly

the word 'frustratingly' is built upon the core verb 'frustrate', which entered english from latin frustratus, meaning 'disappointed' or 'ineffective', itself from frustra ('in vain'). the addition of the '-ing' suffix transforms it into an adjective describing something that causes this state of disappointment. finally, the adverbial suffix '-ly', of old english origin, modifies the adjective to describe the manner in which an action is performed. thus, the literal morphemic journey is from a latin concept of being rendered vain or ineffective, through an english adjectival form, to an adverb describing an action done in a manner that provokes such ineffectiveness or annoyance.

Structure: frustrat (thwart) + ing (adjective suffix) + ly (adverb suffix) frustrat is derived from latin frustratus, the past participle of frustrari meaning 'to deceive, disappoint'. -ing is an english suffix forming present participles and adjectives from verbs. -ly is an english suffix forming adverbs from adjectives.
