The kanji 科 is a 形声文字 (keisei moji), a phono-semantic compound. It is composed of the radical 禾 (kome - rice, grain) on the left side and the phonetic component 斗 (to - a measuring container) on the right. Initially, it may have represented a measuring system or a standard for grain. Over time, the meaning expanded to encompass categorization and classification, evolving into the meanings of "subject," "department," and "branch." The association with grain might be traced to the idea of classifying different types of grains. The phonetic component, 斗, suggests the sound and the underlying idea of measurement.
