sù
raw silk
white; plain, unadorned; vegetarian (food); essence; nature; element; constituent; usually; always; ever
plant growth (龶) + silk threads (糸) = raw, plain, elemental
Raw silk threads were naturally white and unprocessed, making 素 the root concept for plainness, purity, and elemental nature. From 'undyed silk' the meaning extended to anything essential, unadorned, or constitutive.
