The phrase "even though" is used to introduce a contrast between two ideas or facts. It indicates that one situation exists or is true despite the presence of another situation that might suggest otherwise. It emphasizes that the second statement does not change the reality of the first.
The phrase "even though" combines the word "even," from Old English "efen," meaning equal or level, and "though," from Old English "þeah," meaning although or despite the fact that. The combination conveys a sense of equality between contrasting statements.
