neglect, laziness
怠 centers on a lack of effort or attention: neglecting duties and giving in to laziness.
怠 combines 台 (a platform or stand) with 心 (heart/mind), suggesting a mind that is idle or resting, leading to neglect or laziness.
The top part 台 looks like a platform, and the bottom 心 is the heart. Picture your heart lounging on a platform, too lazy to get up and do anything—that's neglect.
For タイ, imagine a lazy person tying a hammock to the platform (台) and sleeping all day: tie -> タイ, and the heart (心) is too lazy to care.
