Usage
What does defeat mean? To defeat someone is to beat them in a competition or contest. As a noun, a defeat is a loss (as in That was the team’s first defeat of the season) and defeat is the state of having lost (as in the agony of defeat). In most cases, the verb beat is a close synonym for defeat, but defeat is more formal (you can beat or defeat someone in a game, but a nation defeats another in war). As a verb, defeat can also mean to thwart or prevent something from happening, but this is less commonly used. Example: The Allies defeated the Axis powers in World War II.

Etymology
Origin of defeat
First recorded in 1325–75; Middle English defeten (verb), from Anglo-French, Old French desfait, past participle of desfaire “to undo, destroy,” from Medieval Latin disfacere, equivalent to Latin dis- dis- 1 + facere “to do”
Explanation
Defeat is the opposite of victory. When you lose, you suffer defeat. When you win, you defeat your enemy. This is a word that's all about losing. In World War II, America and the Allies defeated the Axis powers: we beat them. In basketball, Michael Jordan usually defeated his opponents. Any loss can be called a defeat. When you're disappointed or think that nothing is going right, you feel defeated. If you're determined to win, you could say, "I won't accept defeat!" Some people are so stubborn that even though they've obviously been defeated, they won't admit defeat.
