proxy: [15] Proxy has no etymological connection with ‘closeness’. It is a much contracted form of prōcūrātia, the medieval version of Latin prōcūrātiō ‘caring for, taking care of’. This was a noun derived from prōcūrāre, source of English procure. It originally entered English in the 13th century as procuracy, and gradually shrank via procracy and prokecye to proxy. The semantic notion underlying it is of ‘taking care of another’s interests’. => procure
early 15c., proccy, prokecye, "agency of one who acts instead of another; letter of power of attorney," contraction of Anglo-French procuracie (c. 1300), from Medieval Latin procuratia "administration," from Latin procuratio "a caring for, management," from procurare "manage" (see procure). Also compare proctor (n.). Meaning "person who acts in place of another" is from 1610s.
