黽

It refers to a species of frog in the family Ranidae (true frogs).

The character is a pictograph, modeled after the appearance of a squat frog-like creature.

Over time, the character was also borrowed phonetically (假借, gacha) and came to be associated with other pronunciations and meanings, for example “min” sound: As in 黽勉 (민면), meaning to strive or exert effort.

When used as a radical, 黽 generally conveys meanings related to frogs, toads, or even turtles.

Examples of characters using this radical:

鼈 (byeol, soft-shelled turtle)

鼊 (byeok, a type of turtle)

鼀 (chuk, toad)
