During the Renaissance, too many new Latin and Greek words were borrowed in English. The Renaissance was a period of increased activity in almost every field. The re-discovery of Latin and Greek literature led to new activity in the modern English. Most of the classical words borrowed were ‘learned’ words- i.e. they were used in writing rather than in ordinary conversation. Some of this Greek words borrowed in the sixteenth century are alphabet, basic, chorus, drama, dilemma, epic, irony, pathos; from Latin are area, circus, ignorance, vagary etc.
Most of these borrowings are based on the native formations of classical words, such as, attemptate, factuate, etc. Some classical words were simply taken over. A random list of nouns and adjectives and verbs would show among them: maturity, augmentation, garnish, strange, new etc.
Classical words have been invaluable to the English in terms of metaphysical and natural sciences- philology, zoology, biology, anthropology, anatomy, astronomy, philosophy, telephone (‘tele’ is distance and ‘phone’ is sound or voice), telegraph (‘graph’ is writing). Greek fragments like thermo, hyper, -logy, -nomy, are frequently added with new English words.
Greek scientific words are often used in English language- thermometer, perambulator, geology, astrology, astronomy etc. Greek and Latin suffixes and prefixes have considerably added with the English vocabulary- comrade, ex-king, bi-lingual, international, inter-state etc.
Classical formations were useful in getting new adjectives-
Hybrids are formed with Greek and Latin suffixes and prefixes- starvation, talkative, (suffixes); admiration, mechanic, (prefixes). Jesperson has pointed out that “the classical words adopted since the Renaissance have enriched the English language and have specially increased the number of synonyms”.
