The character 而且 is formed through the combination of two ancient pictographs, each contributing a core conceptual idea that merges into a single cohesive meaning. The first character, 而, originally depicted a beard, a visual metaphor for something that is an extension or natural continuation of a face, thus embodying the abstract sense of "furthermore" or progression. The second, 且, was a pictogram of a ritual stand or ancestor tablet, representing something foundational upon which more is added, implying addition and layering. Together, they form a compound where the inherent notion of one thing (而) being extended is concretely supplemented and reinforced by the next (且), visually and conceptually creating the sense of "and moreover".
