The Germanic tribes who would later give rise to the English language (the notional Angles, Saxon and Jutes) traded and fought with the Latin speaking Roman Empire. Many words (some originally from Greek) for common objects therefore entered the vocabulary of these Germanic people via Latin even before the tribes reached Britain (what is known as the Continental or Zero Period): "anchor", "butter", "camp", "cheese", "chest", "cook", "copper", "devil", "dish", "fork", "gem", "inch", "kitchen", "mile", "mill", "mint" (coin), "noon", "pillow", "pound" (unit of weight), "punt" (boat), "sack", "wall", "street", "wine". Cognates of virtually all of these English words exist in the other Germanic languages.
