Learning notes
Explanation
This botanical term contains ราก, meaning “root.” It specifically refers to the thick central root that grows downward from the stem, helping anchor the plant and absorb water and nutrients. It focuses on the main root rather than the plant's entire root system or its smaller branching roots.
Usage
It is used when discussing plant structure, agriculture, gardening, and transplanting trees. Common patterns include มีรากแก้ว, “to have a taproot,” and รากแก้วหยั่งลึก, “the taproot grows deep.”
Caution
Unlike ราก, which can refer to roots generally, รากแก้ว denotes the thick central taproot. Fibrous roots are called รากฝอย, and the root of a tooth is รากฟัน, not รากแก้ว.
