“Chigaijin” is a pseudo-Japanese compound, with two decompositions. The first one (in green), is “chi-gaijin,” where “gaijin” is a slang term for “foreigner.” The “chi” is in katakana, the script used for loanwords. The second meaning (in blue) is “chigai-jin,” or “different person.” Either way, the “jin” (in red) means person.
