The formation of "并且" is a classical example of Chinese lexical compounding, where two distinct characters, each with their own semantic fields, are combined to create a new, unified meaning. The character "并" originally depicted two people standing side by side, conveying notions of combining, paralleling, or simultaneity. The character "且" is an ancient pictograph of a ritual altar or a sequence, carrying core ideas of furthermore, moreover, or progression. Their fusion into the compound "并且" therefore visually and conceptually merges the sense of linkage or pairing from "并" with the sense of additive sequence from "且", resulting in the modern meaning of "and furthermore" or "in addition".
