Theory of Parts of Speech

 The parts of speech are commonly divided into open classes (nouns, verbs, adjectives, and adverbs) and closed classes (pronouns, prepositions, conjunctions, articles/determiners, and interjections). The idea is that open classes can be altered and added to as language develops and closed classes are pretty much set in stone.

Read about each part of speech below and get started practicing identifying each.

Noun

Nouns are a person, place, thing, or idea. They can take on a myriad of roles in a sentence, from the subject of it all to the object of an action. They are capitalized when they're the official name of something or someone, called proper nouns in these cases. 

Examples: pirate, Caribbean, ship, freedom, Captain Jack Sparrow.

Pronoun

Pronouns stand in for nouns in a sentence. They are more generic versions of nouns that refer only to people. 

Examples:​ I, you, he, she, it, ours, them, who, which, anybody, ourselves.

Verb

Verbs are action words that tell what happens in a sentence. They can also show a sentence subject's state of being (is, was). Verbs change form based on tense (present, past) and count distinction (singular or plural).

Examples: sing, dance, believes, seemed, finish, eat, drink, be, became

Adjective

Adjectives describe nouns and pronouns. They specify which one, how much, what kind, and more. Adjectives allow readers and listeners to use their senses to imagine something more clearly. 

Examples: hot, lazy, funny, unique, bright, beautiful, poor, smooth.

Adverb

Adverbs describe verbs, adjectives, and even other adverbs. They specify when, where, how, and why something happened and to what extent or how often. Examples: softly, lazily, often, only, hopefully, softly, sometimes.

Preposition

Prepositions show spacial, temporal, and role relations between a noun or pronoun and the other words in a sentence. They come at the start of a prepositional phrase, which contains a preposition and its object. 

Examples: up, over, against, by, for, into, close to, out of, apart from.

Conjunction

Conjunctions join words, phrases, and clauses in a sentence. There are coordinating, subordinating, and correlative conjunctions. 

Examples: and, but, or, so, yet, with.

In conclusion, the parts of speech is fundamental power of language. It enables us to construct meaningful sentences, convey our thoughts with precision, and create lasting impacts through our communication. Embrace the diversity of the parts of speech, and you will use the language, elevating your ability to express, connect, and communicate in ways you never thought possible.
