altar of sacrifice, chopping board
爼 centers on a flat surface used in ritual or food preparation: an altar for sacrifices or a chopping board. Both meanings share the idea of a dedicated platform for cutting or offering.
爼 is a variant form of 俎, which combines 爻 (intertwined lines, possibly representing meat or a pattern) with 且 (a stand or altar). Together they depict a ritual cutting board or altar. The exact historical development is uncertain, but the character is associated with sacrificial vessels.
The left side 爻 looks like a crisscross pattern of cuts on a surface, and the right side 且 resembles a raised platform. Picture a wooden board marked with knife scores, used as both a chopping block and a sacred altar.
For ソ, imagine a solemn ritual where a priest places an offering on the altar and says 'So be it.' The word 'so' cues ソ, and the scene ties back to the sacrificial altar meaning.
