authorization
UK: ˌɔːθəraɪˈzeɪʃən | US: ˌɔːθərəˈzeɪʃən
n. The act of giving official permission or approval for something.
n. A document or statement that grants such permission.
n. The power or right to perform certain actions or access resources.
The word "authorization" traces back to the Latin auctor (meaning "originator" or "promoter"), which evolved into Old French autoriser ("to approve"). The English suffix -ize (from Greek -izein) converts nouns into verbs, while -ation (Latin -atio) forms nouns denoting actions or results. Thus, "authorization" literally means "the act of granting originator-like power or approval." The term reflects a hierarchical logic—authority flows from an original source (author) to delegated permissions.
