Among words of Romanic origin borrowed from Latin during the period when the British Isles were a part of the Roman Empire, there are such words as: street, port, wall etc. Many Latin and Greek words came into English during the Adoption of Christianity in the 6-th century. At this time the Latin alphabet was borrowed which ousted the Runic alphabet. These borrowings are usually called classical borrowings. Here belong Latin words: alter, cross, dean, and Greek words: church, angel, devil, anthem.
Latin and Greek borrowings appeared in English during the Middle English period due to the Great Revival of Learning. These are mostly scientific words because Latin was the language of science at the time. These words were not used as frequently as the words of the Old English period, therefore some of them were partly assimilated grammatically, e.g. formula - formulae. Here also belong such words as: memorandum, minimum, maximum, veto etc.
Classical borrowings continue to appear in Modern English as well. Mostly they are words formed with the help of Latin and Greek morphemes. There are quite a lot of them in medicine (appendicitis, aspirin), in chemistry (acid, valency, alkali), in technique (engine, antenna, biplane, airdrome), in politics (socialism, militarism), names of sciences (zoology, physics). In philology most of terms are of Greek origin (homonym, archaism, lexicography).
