permission
UK: pəˈmɪʃ(ə)n | US: pərˈmɪʃ(ə)n
n. the act of allowing someone to do something; formal consent or authorization.
The word "permission" originates from Latin permissio, derived from permittere ("to allow, let pass"). The morpheme per- means "through" (as in "pervasive"), while miss comes from mittere ("to send," seen in words like "mission" or "transmit"). The suffix -ion forms abstract nouns indicating an action or state. Thus, "permission" literally means "the act of sending through" or "allowing passage," reflecting its modern sense of granting consent.
