Standing in what one is without apology. Also the public claiming of an identity others tried to make shameful.
Old English pryto (pride), formed from prud (proud), an early borrowing from Late Latin prode (worthy, advantageous), from prodesse (to be of use): pro- (forth) + esse (to be); pride begins as a claim of worth rather than of arrogance.
Standing in what one is without needing to be excused for it. The public sense — claimed identity worn openly — asks the same question the private sense does: whose worth gets to be said aloud.
