Engrish refers to unusual English originating in Japan, and often by extension other East Asian countries. The term itself arises from the ethnic stereotype that Japanese people often confuse the English phonemes "r" and "l", since the Japanese language has one alveolar consonant in place of both. The word is not used in Japan, as the actual Japanese word for the English language is eigo (wikt:英語).
While the term may refer to spoken English, it is more often used to describe written English. Engrish can be found in many places, including signs, menus, and advertisements. Terms such as Japlish or Janglish for Japan, Konglish for Korea, Singlish for Singapore, and Chinglish for China are sometimes used as well.
