Here's why:
* Old English (Anglo-Saxon): This is the foundation of the English language, primarily influenced by Germanic languages like Old Frisian, Old Saxon, and Old High German.
* Norman French: The Norman Conquest in 1066 brought a significant influx of French words into English, enriching the vocabulary immensely.
* Latin: Latin has influenced English through its role as the language of the Church, education, and law.
* Greek: Greek vocabulary has also influenced English, particularly in areas like science, philosophy, and medicine.
* Other Languages: English has borrowed words from a variety of languages throughout its history, including Scandinavian, Dutch, Italian, Spanish, Arabic, and many others.
It's important to note: English isn't just a "mix" of languages. It has developed its own grammar, pronunciation, and unique vocabulary. While it's influenced by other languages, it stands as a distinct language in its own right.
