The indigenous languages of Malaysia belong to the Mon-Khmer and Malayo-Polynesian families. The national, or official, language is Malay which is the mother tongue of the majority Malay ethnic group. The main ethnic groups within Malaysia are the Bumiputera (which consist of Malays, Orang Asli, and, natives of East Malaysia), Arab Malaysians, Malaysian Chinese and Malaysian Indians, with many other ethnic groups represented in smaller numbers, each with their own languages. The largest native languages spoken in East Malaysia are the Iban, Dusunic, and Kadazan languages. English is widely understood and spoken within the urban areas of the country; the English language is a compulsory subject in primary and secondary education. It is also the main medium of instruction within most private colleges and private universities. English may take precedence over Malay in certain official contexts as provided for by the National Language Act, especially in the states of Sabah and Sarawak, where it may be the official working language. Furthermore, the law of Malaysia is commonly taught and read in English, as the unwritten laws of Malaysia continue to be partially derived from pre-1957 English common law, which is a legacy of past British colonisation of the constituents forming Malaysia. In addition, authoritative versions of constitutional law and statutory law (written laws of Malaysia) are continuously available in both Malay and English.

Malaysia contains speakers of 137 living languages, 41 of which are found in Peninsular Malaysia. The government provides schooling at the primary level in each of the three major languages, Malay, Mandarin and Tamil. Within Malay and Tamil there are a number of dialectal differences. There are a number of Chinese languages native to the ethnic Han Chinese who originated from Southern China, which include Yue, Min and Hakka Chinese.

Many languages are spoken, or historically have been spoken, in Zimbabwe. Since the adoption of its 2013 Constitution, Zimbabwe has 16 official languages, namely Chewa, Chibarwe, English, Kalanga, Koisan, Nambya, Ndau, Ndebele, Shangani, Shona, sign language, Sotho, Tonga, Tswana, Venda, Xhosa. The country's main languages are Shona, spoken by over 70% of the population, and Ndebele, spoken by roughly 20%. English is the country's lingua franca, used in government and business and as the main medium of instruction in schools. English is the first language of most white Zimbabweans, and is the second language of a majority of black Zimbabweans. Historically, a minority of white Zimbabweans spoke Afrikaans, Greek, Italian, Polish, and Portuguese, among other languages, while Gujarati and Hindi could be found amongst the country's Indian population. Deaf Zimbabweans commonly use one of several varieties of Zimbabwean Sign Language, with some using American Sign Language. Zimbabwean language data is based on estimates, as Zimbabwe has never conducted a census that enumerated people by language.

An English-medium education system is one that uses English as the primary medium of instruction—particularly where English is not the mother tongue of students.

Initially this is associated with the expansion of English from its homeland in England and the lowlands of Scotland and its spread to the rest of Great Britain and Ireland, beginning in the sixteenth century. The rise of the British Empire increased the language's spread to British colonies, and in many of these it has remained the medium of education. The increased economic and cultural influence of the United States since World War II has also furthered the global spread of English, as has the rapid spread of Internet and other technologies. As a result of this, there are English-medium schools in many states throughout the world where English is not the predominant language. Also in higher education, due to the recent trend towards internationalization, an increasing number of degree courses, particularly at master's level, are being taught through the medium of English.
