English remains an active second language, with its use allowed for some official purposes under the National Language Act of 1967. In Sarawak, English is an official state language alongside Malaysian. Historically, English was the de facto administrative language; Malay became predominant after the 1969 race riots (13 May incident). Malaysian English, also known as Malaysian Standard English, is a form of English derived from British English. Malaysian English is widely used in business, along with Manglish, which is a colloquial form of English with heavy Malay, Chinese, and Tamil influences. The government discourages the use of non-standard Malay but has no power to issue compounds or fines to those who use improper Malay on their advertisements.
