|Thai is spoken by approximately 20 million people. Thai is the official language in Thailand. The standard is based on the dialect of the central Thai people, and it is written in the Thai alphabet, an abugida script that evolved from the Khmer script. Several other dialects exist, and coincide with the regional designations.
English is spoken by approximately 375 million people as their first language. English is probably the third largest language by number of native speakers, after Mandarin Chinese and Spanish. However, when combining native and non-native speakers it is probably the most commonly spoken language in the world.
