- proper n. Ungrammatical, unorthographical or nonsensical English found in East Asia, especially Japan.
From the mispronunciation of the word "English" common to Japanese speakers who have difficulty distinguishing "L" and "R" sounds. The Japanese transliteration of English - イングリッシュ (Ingurishu) is often used for teaching purposes. In that word /ɽ/ sound (romanised as "r") is pronounced instead of the English /l/. (Wiktionary)
