How do you express "I understand" in Thai?

The expression "I understand" in Thai is represented by the phrase "ฉันเข้าใจ" (chan kao jai). This phrase is made up of three components: "ฉัน" (chan), which means "I," "เข้าใจ" (kao jai), which means "understand." Together, they directly communicate the idea of comprehension in a personal context.

The other options do not convey the same meaning. "เมือง" (mueang) refers to "city," which has no connection to understanding. "เด็ก" (dek) means "child", while "ผมรักคุณ" (pom rak khun) translates to "I love you," expressing a sentiment rather than comprehension. Therefore, the selected phrase is the only correct way to express the concept of understanding in Thai.
