*okw-

1706, "weakening of the eyesight without any apparent defect in the eyes," medical Latin, from Greek amblyōpia "dim-sightedness," noun of action from ōps "eye" (from PIE root *okw- "to see")  + amblys "dulled, blunt," a word of uncertain origin; according to Watkins possibly from a suffixed form of PIE root *mel- (1) "soft." With abstract noun ending -ia. Related: Amblyopic.

1530s, "aged, venerable;" 1540s, "having existed in ancient times," from French antique "old" (14c.), from Latin antiquus (later anticus) "ancient, former, of olden times; old, long in existence, aged; venerable; old-fashioned," from PIE *anti- "before" (from root *ant- "front, forehead," with derivatives meaning "in front of, before") + *okw- "to see."

Originally pronounced in English like its doublet antic, but French pronunciation and spelling were adopted in English from c. 1700. The meaning "not modern" is from 1640s. Related: Antiqueness.
