imperfectly

the word "imperfectly" is built upon the latin foundation of perfectus, the past participle of perficere meaning "to complete" (from per- "thoroughly" + facere "to do, make"). the negative prefix im- (a form of in-) was attached to negate the state of completion, forming "imperfect". this adjective entered english via old french. the old english adverbial suffix -lice (modern -ly) was then appended to create the adverb, describing an action performed in a manner that is not complete, finished, or flawless. thus, the word's logic traces a clear path from the ancient concept of thorough making, through its negation, to the modern sense of doing something with faults or shortcomings.

Structure: im (not) + perfect (complete) + ly (adverb suffix) • im: a latin prefix meaning "not" or "without", a variant of 'in-' used before 'p'. • perfect: from latin perfectus, meaning "completed, finished, accomplished". in english, it means having all the required elements, qualities, or characteristics; flawless. • ly: an old english suffix used to form adverbs from adjectives, indicating manner or degree.
