The word 対戦 is a compound word. 対 (tai) originally comes from the concept of "opposing" or "facing," and it is also related to the English word "against". 戦 (sen) comes from the idea of "war" or "battle". Thus 対戦 literally means "facing a battle" or "competing" against someone or something. The combination of these two kanji gives the word its meaning of competition or a head-to-head match.
