means To refine or smooth something until its rough edges, flaws, or effort disappear, giving it a finished, gleaming quality — literally with a surface, or figuratively with a performance, a draft, a manner.

from From Old French 'polir' (to polish, make smooth), tracing back to Latin 'polire,' meaning to smooth or refine. The root sense was always physical — rubbing a surface until it shines — and English borrowed it whole, later stretching it to cover anything buffed into presentable shape: prose, manners, a rough plan. (Note: this 'polish' is unrelated to 'Polish' meaning of Poland, a coincidence of spelling that trips up many a spellchecker.)
