The word "知识" is formed by combining the character "知", meaning to know, which is itself composed of "矢" (arrow) and "口" (mouth) to suggest the direct and swift transmission of awareness, with the character "识", meaning to recognize or understand, composed of "言" (speech) and "戠" (a phonetic component also associated with marking) to indicate discernment through expressed signs; together they denote knowledge as acquired and recognized understanding.
