English became the 'most gloriously, empire language' primarily due to the vast expansion of the British Empire during the 18th, 19th, and early 20th centuries. As Britain established colonies across the globe in North America, Australia, Asia, and Africa, English was introduced as the language of administration, law, and education. This political and economic dominance ensured that English spread to every corner of the world, absorbing words from many other languages and establishing itself as a prestigious global language.
