The official languages of Singapore
[...] Most Singaporeans speak a localized dialect of English called Singlish or Singaporean English, which can be difficult for foreigners to understand at first. Singlish is based on standard English with influences and loan words from Chinese, Malay and Indian languages. Singapore is a multilingual society, which is why Singlish developed over time. Singlish phrases are most common in the informal aspects of the English language, such as casual conversation. In school, every student learns English and a second language of their choice. Mandarin is the second most popular language, with over 70% of the population speaking it as a first or second language.Wikipedia has more details on the Languages of Singapore.
