embryo
胚 centers on the earliest stage of development: an embryo, the beginning form of life before it takes shape.
胚 combines the flesh component ⺼ with 丕, which likely contributes the sound and may relate to the idea of something not yet fully formed.
The flesh component ⺼ on the left suggests a body part, and 丕 on the right looks like a sprout pushing up from the ground. Together, picture the earliest fleshy sprout of life: an embryo.
For ハイ, imagine a tiny embryo saying 'Hi!' as it begins to grow: Hi -> ハイ, a small greeting from the earliest stage of life.
