Classical poetry and literature contain many puns and allusions based on similarities of sound or form between characters, so that if, for instance, 傑 (' chieh '--' outstanding ') is written as 杰, or 適 (' shih' - 'suitable') as 适 (traditionally read'k'uo '--' swift '), then is the meaning the same or is some allusion implied?
因為古詩文有許多形聲轉借字，如將「傑」作「杰」，「適」作「适」（音ㄎㄨㄛˋ）等，究竟是同義，還是另有假借？
