The kanji 張 is a phono-semantic compound (形声文字; けいせいもじ). The phonetic component is 長 (chou, meaning "long" or "grow"). The semantic component is 弓 (yumi, meaning "bow"). The original meaning was likely related to stretching a bowstring, thus linking the concept to "stretching" or "extending." Over time, the character evolved to encompass broader meanings of expansion and establishing something.
