I am writing an essay and i really don't want to use the word 'very' to go with another word. Is there a different word that I can use?

This may be the most common problem confronted by writers. There are many different words you can use, or you might decide not to use an intensifier like "very" at all. Some examples of synonyms or near-synonyms for "very" are "quite," "exceedingly," "remarkably," "really," or "particularly." But if you look back at your essay, you may decide that you can perhaps come up with adjectives that are strong enough that the word "very" or the like are not needed at all. Instead of saying something is "very useful," for example, you might say that it is "essential" or "indispensable." Rather than being "very fast," a person might be said to be "speedy" or "fleet of foot." In fact, eliminating unnecessary adverbs can make one's writing more clear and elegant. It is also the reason that developing an extensive vocabulary is so important--by expanding your vocabulary, you can sometimes use one word instead of two or three and achieve a greater precision of meaning.
