impermissibly

the word "impermissibly" is built upon the latin verb 'permittere', which itself is a compound of 'per-' ("through, thoroughly") and 'mittere' ("to send, let go"). the core notion is of sending something through, thereby allowing it. the negative prefix 'im-' (from latin 'in-') reverses this meaning to "not allow". the suffix '-ibly' transforms the adjective "impermissible" into an adverb, describing the manner of an action. thus, the literal morphemic journey from "not to send through" evolves into the modern abstract sense of acting in a forbidden way.

Structure: im (not) + permiss (allow) + ibly (adverb suffix) - im: a latin prefix meaning "not", a variant of 'in-' used before 'p', 'b', or 'm'. - permiss: from the latin root 'permiss-', the past participle stem of 'permittere', meaning "to allow, let through". - ibly: a latin-derived adverbial suffix, a variant of '-ably', meaning "in a manner that can be [verb]ed".
