All words belong to categories called word classes (parts of speech) according to the part they play in a sentence.
The main word classes in English are listed below:
Nouns:
Nouns are words for people, animals, places, foods, states or things like: mother, dog, Rome, pizza, happiness and car.
Pronoun:
Pronouns are used in place of a noun that is already known or has already been mentioned. This is often done in order to avoid repeating the noun.
Skyler left early because she was tired.
Hank brought the gun with him.
Personal pronouns can be divided into various categories according to their role in a sentence, as follows:
– Subjective pronouns
– Objective pronouns
– Possessive pronouns
– Reflexive pronouns
Adjective:
An adjective is a word that describes a noun, giving extra information about it.

Verb:
A verb describes what a person or thing does or what happens.
Main verbs: jump, stop, snow
Help verbs: be, modals, etc.
Adverb:
An adverb is a word that is used to give information about a verb, adjective, or other adverbs. They can make the meaning of a verb, adjective, or other adverbs stronger or weaker.

Preposition:
A preposition is a word such as after, in, to, on, and with. Prepositions are usually used in front of nouns or pronouns and they show the relationship between the noun or pronoun and other words in a sentence.

Conjunction:
A conjunction (also called a connective or linking word) is a word such as and, because, but, for, if, or, and when. Conjunctions are used to connect phrases, clauses, and sentences.

Determiner / Article:
A determiner is a word that introduces a noun, such as a/an, the, every, this, those, or manyas in a dog, the dog, this dog, those dogs, every dog, many dogs.
Interjection / Exclamation:
An interjection (also called an exclamation) is a word or phrase that expresses strong emotion, such as surprise, pleasure, or anger.
Exclamations often stand on their own, and in writing they are usually followed by an exclamation mark rather than a full stop.
Interjections have no grammatical value – words like: ah, hey, oh, ouch, um, well, and yuck.
