Manglish is an informal form of Malaysian English with features of an English-based creole principally used in Malaysia. It is heavily influenced by the dominant languages of the country, Malay, Chinese languages, and Tamil. It is not an official language of Malaysia.
Manglish spoken in West Malaysia is very similar to and highly mutually intelligible with Singlish, a creole of similar roots. There is little distinction between the two creoles except that Manglish vocabulary contains more Malay words while Singlish contains more words of Hokkien (Min Nan) and Teochew origin.
The vocabulary of Manglish consists of words originating from English, Malay, Hokkien, Mandarin, Cantonese, Tamil, and, to a lesser extent, various other European languages and Arabic, while Manglish syntax resembles southern varieties of Chinese. Also, elements of American and Australian slang have come through from imported television series.
The Malaysian Manglish is sometimes known as Rojak or Bahasa Rojak,
