means a deep sense of satisfaction in one's own achievements, possessions, or those of someone close — or, taken too far, an inflated regard for one's own importance.

from From Old English 'prȳde,' a noun spun off from 'prūd' (proud), which itself was likely borrowed from Old French 'prud' or 'prod,' meaning brave, valiant, or excellent. Curiously, the word seems to have traveled into French from the Late Latin 'prode' (useful, advantageous) before bouncing back across the Channel — so the very idea of being 'proud' arrived in English as a foreign import that the English then made entirely their own. The 'lion's pride' sense (a group of lions) is much later and unrelated in spirit, borrowing the word's sense of splendor and showy magnificence.
