Parts of a speech can be defined as word categories that share the same grammatical properties or DNA, and they’re the foundation upon which grammar is founded. All English words fall under parts of speech, and at times, they can be confusing since they have different syntactic functions. As a person who engages in English writing regularly, identifying parts of speech issues can be extremely challenging. 

You need mastery of the language, a deep understanding of sentence structure, and most importantly, the different categories of parts of speech. Luckily for you, you don’t have to break a sweat doing all that, as our online part of speech identifier can help with all that. It analyzes your written texts, profiles them depending on their morphological characteristics, and then identifies and corrects any underlying issues.

But before we jump the gun, let’s take a look at the different categories of parts of speech depending on their different syntactic functions.

Different Categories of Parts of Speech

Basically, parts of speech can be divided into two main categories i.e open classes and closed classes. Open classes can further be extrapolated into verbs, nouns, adverbs, and adjectives, whereas closed classes include prepositions, pronouns, conjunctions, interjections, and determiners. 

The main difference between the two is that open classes can be amended, whereas closed classes are more or less set in stone and can’t be altered. Let’s briefly take a look at each category in depth, and how our parts of speech finder tool can help:


Nouns are used to refer to a person, place, thing, or even idea. They can be used in a sentence as the main subject, subject complement, direct object, indirect object, or even object of a preposition. Still, they can be plural or singular, abstract or concrete, and paired with an article (a, an, the), although not always. 

Our parts of speech online checker will help identify sneaky wrong noun usage mistakes in your texts and allow you to correct them with a single click of a mouse.


Pronouns are words or phrases used to replace nouns in a sentence, and more precisely, antecedents. Basically, an antecedent of an event or something happens or exists before the thing or the event itself. 

There are several types of pronouns including:

  • Personal pronouns. Refers to a specific person or thing.
  • Possessive pronouns. Used to indicate ownership.
  • Reflexive pronouns. Used to denote another pronoun or noun. 
  • Relative pronouns. Used to introduce subordinate clauses in a sentence.
  • Demonstrative pronouns. Helps identify nouns. 

Depending on the pronouns you intend to use in your texts, there are different rules that you need to keep in mind. If you are an average person, you choose to either note all these rules somewhere in a book or use a sentence checker for parts of speech like ours. Not only will it help rid your texts of wrong pronoun usage but also many other mistakes that may escape the bare eye.


Verbs are action words used to express an action or being in a sentence. Verbs can change form depending on count distinction (plural or singular) and tense (past or present). Common verbs include words such as believes, dance, sing, finish, eat, be, became, and drink. 

Unfortunately, using verbs in their correct tense form can be confusing and equally challenging, especially for non-English native speakers. Luckily for you, our online identify parts of speech checker can easily pinpoint verb tense issues and recommend corrections to fix them.


Adverbs are used to describe or modify verbs, adjectives, or other adverbs, but not nouns. They usually provide answers to questions of where, when, why, how, or to what extent. They mainly end in -ly and include words such as carefully, gently, and extremely.


Unlike their adverb counterparts, adjectives are used to describe or modify nouns and pronouns. They provide specificity to questions of which one, what kind, how much, and more. Common examples include hot, funny, lazy, unique, beautiful, bright, and poor.

The huge number of adjectives and rules governing them pose a major challenge to students and professional writers alike in terms of application. Our part of a speech checker can help identify and correct adjective-related mistakes in your texts, ultimately improving their readability.


Typically placed before pronouns, nouns, or noun phrases, prepositions are used to introduce an object or show time, place, direction, and spatial relationships in a sentence. They play a role similar to that of an adverb or an adjective and include words such as with, about, until, and by.


As the name suggests, conjunctions are used to join words and clauses in a sentence. There are three main types of conjunctions namely, coordinating conjunctions, subordinating conjunctions, and correlative conjunctions. Common examples include and, or, but, yet, so, and with.


Articles and Determiners

Just like adjectives, articles and determiners are used to modify nouns in a sentence. The only difference is that articles and determiners are used to improve the syntax of a sentence. In other words, they help identify and specify nouns. There are two categories of articles;

  • Indefinite articles. Used to describe something for the first time (a drink) or refer to a particular member of a class or group (a doctor). 

  • Definite articles. Used to refer to specific things/groups (the blue house) or describe a previously identified thing/group (The Pope)

Interjections are words or phrases used to express emotion in a sentence and are mainly followed by an exclamation mark. They include: Oh!, Wow!, and Oops!
