Today a certain Philippine English, as formally called based on the World Englishes framework of renowned linguist Braj Kachru, is a recognized variety of English with its distinct lexical, phonological, and grammatical features (with considerable variations across socioeconomic groups and level of education being predictors of English proficiency in the Philippines). As English language became highly embedded in Philippine society, it was only a matter of time before the language was indigenized to the point that it became differentiated from English varieties found in the United States, United Kingdom, or elsewhere. This, along with the formal introduction of the World Englishes (WE) framework to English language scholars in the Philippines opened the floodgates to research on this new emerging English, which has since been branded as such as Philippine English.[15]
