offerings to gods
胙 centers on ritual offerings, specifically meat or food presented to gods or spirits. The meaning is narrow and ceremonial.
胙 combines the flesh radical ⺼ with 乍, which likely contributes the sound. The character is associated with meat offerings in ancient ritual contexts.
The flesh radical ⺼ on the left suggests meat, and the right side 乍 looks like a person kneeling at an altar. Imagine a kneeling figure presenting meat as an offering to the gods.
For ソ, picture a solemn offering of meat placed on a stone altar: the word 'solemn' starts with 'so', cueing ソ.
