The word "authorisation" derives from the root "author," which originates from the Latin auctor (meaning "originator" or "creator"). The suffix "-ise" (or "-ize") is a verb-forming suffix from Greek -izein, indicating the act of making or causing. The suffix "-ation" (from Latin -atio) converts the verb into a noun, denoting the process or result of the action. Thus, "authorisation" literally means "the act of granting originator-like power or approval."
