Parts of Speech

An open word class indicates the fact that new words can be added to it over time as the language evolves and changes. The following is a list of open parts of speech:

A closed (or functional) word class refers to groups that include a limited number of words and other words cannot be added to them. For example, new nouns are created every day, but articles never change.
The following is the list of closed parts of speech:

Nouns are words that are used to refer to people, places, things, or concepts. Nouns can serve as the subject or object in a sentence.
We have different types of nouns, such as proper and common, collective, concrete and abstract, etc. Take a look at some examples:

Verbs are words that tell us about the action or state of the subject. Verbs can take different forms based on their tense and number. We have different types of verbs, such as modals, auxiliaries, or linking verbs. Here are some examples:

Pronouns are words that replace a noun (or a noun phrase) to avoid unnecessary repetition of the noun or noun phrase. We have different types of pronouns, such as personal, possessive, and reflexive pronouns. Here are some examples:

Adjectives describe or modify nouns and pronouns. Adjectives give us information about the quality, size, number, and many other features of nouns or pronouns. We have different types of adjectives, such as attributive, gradable, descriptive, etc. Here are some examples:

Adverbs describe or modify verbs, adjectives, and sometimes other adverbs. They give us more information about when, where, how, why, to what extent, or how often something happens. We have different types of adverbs, such as adverbs of place, manner, degree, frequency, etc. Here are some examples:

Prepositions are words that appear before a noun or pronoun and describe the relationship between words (such as a verb and a noun). We have different types of prepositions, such as place, time, direction and movement, etc. Here are some examples:

Determiners are words that come before nouns and, like adjectives, modify them. However, they are different from adjectives in that they are essential for the completeness of the sentence. We have different types of determiners, such as possessive, interrogative, demonstrative, articles, etc. Here are some examples:

Conjunctions are words that join one word, phrase, or clause to another word, phrase, or clause. We have different types of conjunctions, such as coordinating, subordinating, and correlative conjunctions. Here are some examples:

Interjections (also called exclamations) are words that show people's emotions and reactions to events and situations. We have different types of interjections, such as interjections of greeting, joy, surprise, sorrow, understanding, etc. Here are some examples:
