Philippine English (similar and related to American English) is any variety of English native to the Philippines, including those used by the media and the vast majority of educated Filipinos and English learners in the Philippines from adjacent Asian countries. English is taught in schools as one of the two official languages of the country, the other being Filipino (Tagalog). Due to the influx of Filipino English teachers overseas, Philippine English is also becoming the prevalent variety of English being learned in the Far East as taught by Filipino teachers in various Asian countries such as Korea, Japan and Thailand, among others. Due to the highly multilingual nature of the Philippines, code-switching such as Taglish (Tagalog-infused English) and Bislish (English infused with any of the Bisayan languages) is prevalent across domains from casual settings to formal situations.

After a tumultuous period of colonial transition, Filipino leaders and elites, and the American colonial government alike begun discussing the formation of a Philippine national language. The retained high ethnolinguistic diversity of the new colony was due to low penetration of Spanish under Spain's rule. Spanish was limited to a medium of instruction for the landed elites and gentry. At the end of Spanish colonization, only 3-5% of the colonial population could speak Spanish. The lingering effects of Spanish amongst the general population nevertheless had notable effects on the lexical development of many Philippine languages, and even Philippine English, in the form of hispanisms. Tagalog was selected to be the basis for a national language in 1937, and has since remained so. It was re-labelled as Pilipino in 1959, and Filipino in 1987.
