存

存 is a phonosemantic compound character, made up of:

子 (자) – “child” (semantic component), suggesting continuation or being

才 (재) – providing the sound.

There are other characters meaning “to exist” or “to have,” such as:

在 (있을 재) – indicates being at a place (to be located)

有 (있을 유) – indicates possession (to have something)

存 focuses on existence itself, often implying continuance or preservation, while 在 and 有 have slightly different shades of meaning.
