Final answer:
Latin, Greek, French, and German significantly contributed to the shaping of the English Language.
Step-by-step explanation:
The four source languages that significantly contributed to the shaping of the English language are Latin, Greek, French, and German. Latin had the biggest influence on English, as it was the language of the Roman Empire and provided the foundation for many vocabulary words. Greek also had a significant impact, particularly on fields such as science, medicine, and philosophy. French, due to the Norman Conquest of England in 1066, introduced a large number of words into English. Lastly, German, as a Germanic language like English, shares many common roots and vocabulary with English.
