complicitous

the word 'complicitous' is a modern english formation built upon the older noun 'complicity'. its core, the latin verb plicare, meaning "to fold", gave rise to a figurative sense of being entangled or involved. the prefix 'com-' intensifies this notion of being folded or woven together with others. thus, the literal sense of "folded together" evolved into the modern abstract meaning of being jointly involved, especially in a wrongful act. the suffix '-ous' then converts this state into an adjectival form, characterizing someone as being full of such shared involvement.

Structure: com (together) + plicit (folded) + ous (adjective suffix) com: latin origin, a prefix meaning "together, with". plicit: from latin plicare (to fold), a bound root appearing in english as -plicit. ous: latin suffix -osus, forming adjectives meaning "full of, characterized by".
