Etymology
the word 'improperly' is built upon the core adjective 'proper', which originates from the latin 'proprius', meaning "one's own" or "particular to itself," thus conveying the sense of what is correct or fitting. the negative prefix 'im-', a variant of 'in-' used before labial consonants, was attached to form 'improper', meaning "not correct." finally, the old english adverbial suffix '-ly', a prolific and stable morpheme in the language, was added to create the adverb describing an action performed in an incorrect or unsuitable manner. this construction elegantly demonstrates the layering of latin negation onto a latin root, followed by germanic grammatical modification to form a modern english adverb.
