Yes, by any definition. First, the English language was and is derived from many cultures and many other languages. While beginning with the languages of pre-Renaissance culture and nomadic tribes such as Angles, Saxon, Jutes, Celts, etc., it very quickly added Latin and Greek words and syntax. Then, in the Age of Discovery, The English colonization, trade, and imperialism of other continents brought English to other cultures, especially to the ruling class. French, Spanish, and other European languages were absorbed (for example, as a result of the Norman Invasion) into the English language. The rise of America as a world trade power strengthened the language further. The, after two world wars, the world got used to the English language as a common denominator, even in the Orient, where the languages were based on syllables rather than individual letters. Today, in cross-cultural business transactions, English is universally accepted as the shared language and the preferred second language in all countries (for example, India). It is still absorbing vocabulary from other tongues.
