The primary difference between “complains” and “complaints” is their part of speech. Complains is a verb that describes the action of expressing dissatisfaction, whereas complaints is a plural noun that refers to the actual statements of dissatisfaction themselves. Consequently, you use “complains” for actions (e.g., “He complains often”) and “complaints” for things (e.g., “We received three complaints”).
Choosing between complains or complaints can confuse even experienced writers. While these two words look and sound similar, they perform completely different jobs in a sentence. Mixing them up can make your professional emails, customer service responses, or academic papers look unprofessional. Therefore, understanding how to use each word correctly is essential for clear communication.
This comprehensive guide will break down the rules surrounding complains or complaints. We will explore their definitions, look at real-world examples, and analyze common mistakes. Additionally, you will find practice exercises to test your knowledge. By the end of this article, you will confidently choose the right word every single time.
If you are looking for a quick way to remember the rule, think about action versus object. Specifically, “complains” is an action word, while “complaints” is a object word.

Definition and Explanation
To understand the core difference between these terms, we must look at how they function grammatically within English sentences.
What is “Complains”?
The word complains is the third-person singular form of the verb to complain. It indicates that someone is actively voicing pain, dissatisfaction, or resentment in the present tense. Because it is a verb, it always requires a singular subject like he, she, it, or a specific person’s name.
Grammar Note: Subject (Singular) + Complains
For example, in the sentence “The customer complains about the slow service,” the word complains acts as the action performed by the customer.
What is “Complaints”?
In contrast, complaints is a plural noun. It represents the plural form of complaint. A complaint is a statement that a situation is unsatisfactory or unacceptable. Because complaints is a noun, it can serve as the subject or the object of a sentence. It often follows adjectives, possessive pronouns, or articles like the or many.

Regional and Global Usage
English speakers across the globe recognize both words, yet subtle contextual variations exist in international business communication.
In British and Australian legal systems, the word complaints often triggers formal statutory procedures. For instance, a citizen lodges official complaints with an ombudsman. Meanwhile, American corporate environments frequently replace the noun complaints with euphemisms like “feedback” or “support tickets” to soften the tone. However, the grammatical mechanics of complains versus complaints remain identical across all global dialects, including American, British, Canadian, and Australian English.
Common Mistakes and Corrections
People frequently substitute one word for the other because they confuse the singular noun complaint with the verb complains. Let us look at some typical errors and how to fix them.
Mistake 1: Using the Verb Instead of the Plural Noun
- Incorrect: The company received many complains about the software bug.
- Correct: The company received many complaints about the software bug.
Why it is wrong: The word “many” modifies nouns, not verbs. Therefore, you must use the plural noun complaints.
Mistake 2: Using the Noun Instead of the Verb
- Incorrect: He always complaints when the project deadline changes.
- Correct: He always complains when the project deadline changes.
Why it is wrong: The sentence lacks a verb to show what the subject (“He”) is doing. Thus, complains is required.
Mistake 3: Confusing “Complaint” (Singular) with “Complains” (Verb)
- Incorrect: This is a formal complains against the vendor.
- Correct: This is a formal complaint against the vendor.
Why it is wrong: The article “a” signals that a singular noun must follow. If you mean one item, use complaint. If you mean multiple items, use complaints.
