Answer 1

A noun is a part of speech that is used to name a person, place, thing, quality, or action. A noun can function as asubject,object, complement, appositive, or object of a preposition.

Answer 2

There are a lot of definitions for “noun,” from the simple list to the complex linguistic explanation, but the best way to explain what a noun is is to explain what a noun does. Remember when you read that verbs do verb-y things? Well, here are the noun-y things that nouns do:

They come with articles. If it follows "a," "an" or "the" fairly closely, it’s probably a noun. If there’s an adjective in there, it’ll be between the article and the noun, so you’ll have to ask yourself, “Is this something I can feel, see, smell, taste or touch? Or does it describe something I can feel, see, smell, taste or touch?” If it’s the former, it’s a noun. If it’s the latter, it’s probably an adjective.They are described by adjectives. If something is described as being blue, old, shiny, hot or wonderful (all adjectives), it’s probably a noun.They act as subjects. Generally, the subject of a sentence is the thing that comes right before the verb. When you say, “The Dingo ate my baby,” the subject is “the Dingo.” It comes right before the verb (ate). Subjects are a little tricky because they can consist of just one word or a whole, long phrase that can contain several nouns. Gerund and infinitive verbs can also act as subjects of a sentence, but in that role, they are serving as nouns. Why? Because nouns act as subjects.They act as objects and complements. Complements follow state-of-being verbs like “be,” “seem” and “become.” Objects follow other verbs as well as prepositions. In the sentence, “Amy is a teacher,” the complement is “a teacher.” In the sentence, “Billy hit a teacher,” the object is “a teacher.” In the sentence, “I am sitting near a teacher,” the prepositional object is “a teacher.” In all cases, “teacher” is a noun.They are names. All names of all things (people, cities, towns, counties, states, countries, buildings, monuments, rivers, mountains, lakes, oceans, streams, natural disasters, books, plays, magazines, articles, songs, works of art, etc.) are nouns.

Not all nouns do all of these things all of the time, and not all the words that do some of these things are nouns, but by and large, if it looks like a noun and acts like a noun, it’s probably a noun.
