Final answer:
English belongs to the Indo-European language family, Germanic branch, and West Germanic group.
Step-by-step explanation:
English is a West Germanic language in the Indo-European language family, whose speakers, called Anglophones, originated in early medieval England.
Old English originated from a Germanic tribal and linguistic continuum along the Frisian North Sea coast, whose languages gradually evolved into the Anglic languages in the British Isles, and into the Frisian languages and Low German/Low Saxon on the continent.
Like Icelandic and Faroese, the development of English in the British Isles isolated it from the continental Germanic languages and influences, and it has since diverged considerably.
English is either the official language or one of the official languages in 59 sovereign states (such as in India, Ireland, and Canada). In some other countries, it is the sole or dominant language for historical reasons without being explicitly defined by law (such as in the United States or United Kingdom).
