Which language's vocabulary contributes approximately 60% of the English language?

The vocabulary that contributes approximately 60% of the English language primarily comes from Latin. This stems from historical factors, including the Roman occupation of Britain and the influence of the Church, particularly during the Middle Ages when Latin was the language of education and scholarship. Additionally, many scientific, technical, and legal terms are derived from Latin, further solidifying its significant presence in English. The roots in Latin not only enrich the language but also provide a foundation for much of the specialized vocabulary we encounter today. This deep integration of Latin into various fields of study is a key reason why it is recognized as a primary source of English vocabulary.
