To sharpen; to grind; to whet; to polish; to wash (rice). A versatile verb covering the physical act of honing or cleaning by friction.

A Group 1 (godan) verb with the -ぐ ending. 研ぐ covers sharpening blades (包丁を研ぐ — to sharpen a kitchen knife), polishing surfaces, and also washing rice (米を研ぐ), where the rice grains are rubbed together to remove excess starch. The rice-washing sense is uniquely Japanese and culturally significant. The kanji 研 also appears in 研究 (research) and 研修 (training), all sharing the core idea of refinement through effort.
