How do you say "fast" in Thai?

The term "fast" in Thai is conveyed by the word "เร็ว." This word is used to denote quickness or speed, whether in reference to movement or activity. It can be applied in various contexts, such as describing a speedy car, rapid actions, or quickly completed tasks.

In Thai, the other options represent different meanings: "ช้า" means "slow," indicating a lack of speed; "หนาว" refers to "cold," describing temperature rather than speed; and "ร้อน" translates to "hot," which again focuses on temperature. Understanding these distinctions is crucial for accurate communication in Thai, as each word serves a specific purpose.
