Details

The keyword for 材 is raw material. This kanji refers to substances in their unprocessed or basic state, particularly wood or timber that has yet to be shaped into a finished product. By extension, it also conveys the idea of material, resources, or talent — anything that serves as the foundational stuff from which something useful or valuable can be made. It emphasizes potential and utility before refinement or completion.
