Indonesian and Malay
Indonesian is the official language of Indonesia. Indonesia is a linguistically diverse region; most Indonesians, aside from speaking the national language, are fluent in at least one local language which is commonly used at home and within the local community. The Indonesian language acts as a lingua franca and borrowed heavily from local languages of Indonesia such as Javanese, Sundanese, Minangkabau, etc.
Malay is the official language in Indonesia, Malaysia, Brunei and Singapore. Modern Malay is greatly influenced by English and many words are borrowed from English such as Agustus (August), balkon (balcony), cek (check) and telepon (telephone). Indonesian and Malay are very similar that there is no problem with communication between the peoples of Indonesia and Malaysia. Both languages belong to the Austronesian family.
