foolish, folly, absurdity, stupid
愚 centers on a lack of good sense or judgment: foolishness, stupidity, or absurdity. It describes actions, ideas, or people that are unwise or irrational.
愚 combines 心 (heart/mind) with 禺, which likely contributes the sound and may have originally depicted a monkey or a foolish creature, together suggesting a foolish mind.
The top part 禺 looks like a silly monkey, and the bottom 心 is the heart/mind. Picture a monkey's mind: foolish and making stupid choices.
For グ, imagine a foolish person saying 'goo goo' like a baby: goo -> グ, and the monkey-minded person acts absurdly.
