Singapore is mainly populated by 3 ethnic groups; Chinese, Malay and Tamil. The influence of each of these cultures has blended to create not only a very distinct food culture but also a very unique way of speaking. Most Singaporeans are at least bilingual being able to speak English and either Malay, Mandarin or Tamil. You will often see Singaporeans mixing up their known languages to create Singaporean Slang: Singlish. You will also probably hear Singaporeans add a 'lah', 'leh' or 'lor' to their sentences.
