Most people on this forum are no doubt familiar with some of the basic English grammar I will be discussing in this post but its always good to refresh such stuff. English obviously consists of words and the words used in the English language fall under different categories. Two of those categories are nouns and verbs. Now to start off with nouns, nouns are "words that function as the name of some specific thing or set of things, such as living creatures, objects, places, actions, qualities, states of existence, or ideas." To put it simply you could say that nouns are "people, places, or things." Nouns can fall into two categories, concrete and abstract. Words such as "boy," "girl," and "tree" are examples of concrete nouns. Concrete nouns are nouns that you can touch or at least observe with one or more of the five senses. Abstract nouns are non physical nouns that you can't touch or observe with the five senses. For instance, "love," "hate," and "fortitude" are examples of abstract nouns. Then there are verbs. Verbs are words that function as actions. For instance the words "walk," and "run," are examples of verbs. Now, there are some words that can be either nouns or verbs depending on how they're used. For instance, the word "building" is one such word. A "building" can be the physical structure or it can be the act of making something. Take for instance the sentence, "Elvis has left the building." In that case the word, "building" is being used as a noun. You can also have a sentence such as, "He is building a sand castle." In that case the word "building" is being used as a verb. There are also some instances where a noun can be either a concrete noun or an abstract noun depending on how it's used. Now some people are probably wondering why I've made such a post, well, Im hoping to clear up some miscommunication that sometimes occurs on this forum.
