Complains Or Complaints: Which One Is Correct?

If you have ever paused mid-sentence wondering whether to write “she complains about the noise” or “she has three complaints about the noise,” you are not alone. Complains and complaints look similar, sound similar, and both come from the same root word, but they are not interchangeable. Complains is a verb form, and complaints is a noun form, so the correct choice depends entirely on the job the word is doing in your sentence.

Getting this right matters more than it might seem. Mixing up complains and complaints is one of the most common small grammar slips in everyday English, especially in phrases like “no complains” instead of the correct “no complaints.” Once you understand the simple rule behind the two words, you will never second guess yourself again.

The Simple Difference Between Complains And Complaints

Here is the short answer before we go further.

• Complains is a verb. It describes an action, something a person does. Example: He complains about the weather.
• Complaints is a noun. It describes a thing, specifically a statement of dissatisfaction. Example: He has no complaints about the weather.

Both words come from the base verb “complain,” which means to express dissatisfaction, discomfort, or pain about something. The difference between complains and complaints is purely a matter of grammar, not meaning. One is an action word, and the other is a naming word.

Complains: The Verb Form

Complains is the third person singular present tense of the verb “complain.” You use it when the subject of your sentence is a single person or thing being referred to as “he,” “she,” or “it.”

Basic pattern:

Subject	Verb Form
I / You / We / They	complain
He / She / It	complains

Examples in a sentence:

• She complains every time the bus is late.
• The child complains of stomach pain almost every night.
• My neighbor never complains about anything.

Notice that complains always needs a subject and often a preposition like “about” or “of” to introduce what the complaint concerns.

Complaints: The Noun Form

Complaints is the plural form of the noun “complaint.” A complaint is a specific statement expressing dissatisfaction, discomfort, or an objection. When there is more than one, or when you are speaking generally about complaints as a category, you use the plural form.

Examples in a sentence:

• I have no complaints about the service.
• The company received several complaints last week.
• Customer complaints dropped after the new policy started.

Because complaints is a noun, it typically follows verbs like “have,” “receive,” “file,” “make,” or “raise,” and it can be counted: one complaint, two complaints, no complaints.

Is It “No Complains” Or “No Complaints”?

This is one of the most frequently searched versions of this question, so it deserves a direct answer.

“No complaints” is correct. “No complains” is incorrect.

The reason is simple: “no” modifies a noun, not a verb. You say “no problems,” “no issues,” or “no complaints,” never “no problem,” “no issue,” or “no complain” used as the action word after “no.” Since complaints is the noun, it is the only form that fits after “no.”

✅ Correct: I have no complaints so far.
❌ Incorrect: I have no complains so far.

Even though “no complains” is a very common typing mistake, especially in fast writing or casual messages, it is never grammatically correct in standard English.

Complains Or Complaints In A Sentence: Side By Side

Seeing both words used correctly in similar contexts often makes the rule click faster.

Sentence With Complains	Sentence With Complaints
He complains about his workload daily.	He has several complaints about his workload.
The customer complains loudly at the counter.	The store logged the customer’s complaints.
She never complains, even when tired.	She has zero complaints about the trip.

In every pairing above, the meaning is related, but the grammatical role changes. Complains is always doing something. Complaints is always naming something.

Do We Say “Complains Of” Or “Complains About”?

Both prepositions exist, but they are used in slightly different situations.

• Complains of is common in physical, medical, or sensory contexts. It usually introduces a symptom or sensation.
• The patient complains of chest discomfort.
• The child complains of dizziness at bedtime.
• Complains about is more general and covers everyday dissatisfaction with situations, people, or circumstances.
• He complains about traffic every morning.
• She complains about the cold weather.

This distinction is especially useful in medical or clinical writing, where “complains of” is standard phrasing used to describe a patient’s reported symptoms, such as “patient complains of chest discomfort” or “child complains of stomach pain.”

Common Mistakes With Complains And Complaints

Here are the errors people make most often, along with the correct version.

⚠️ Mistake: I have no complains about my job.
✅ Correct: I have no complaints about my job.

⚠️ Mistake: She always complaints about small things.
✅ Correct: She always complains about small things.

⚠️ Mistake: He filed a complain with the manager.
✅ Correct: He filed a complaint with the manager.

A quick way to catch the mistake yourself: if the word follows “a,” “the,” “no,” “many,” “several,” or a number, it should be the noun form, complaint or complaints. If the word follows a subject like “he,” “she,” or “it” and describes an action, it should be the verb form, complains.

Pronunciation

Both words are pronounced similarly, with the stress on the second syllable.

• Complains: kuhm-PLAYNZ
• Complaints: kuhm-PLAYNTS

The only real difference in sound is the final consonant cluster. Complains ends in a soft “nz” sound, while complaints ends in a sharper “nts” sound because of the added “t” from the noun form “complaint.”

Origin Of The Word

The word complain comes from the Old French “complaindre,” which traces back to the Late Latin “complangere,” meaning to lament or bewail, formed from “com-” (intensifying prefix) and “plangere” (to strike, or to lament by beating one’s chest). Over time, the word entered Middle English and gradually took on its modern meaning of expressing dissatisfaction or grievance, rather than the more dramatic sense of mourning found in its Latin root.

The noun form, complaint, developed alongside the verb and has long been used both in everyday speech and in formal contexts, such as legal complaints, medical complaints, and customer complaints.

Complains Or Complaints In Different Contexts

In everyday conversation: People usually use complains to describe a habit or ongoing behavior, such as “my husband complains about everything,” and complaints to summarize the general feedback someone has given, such as “I really have no complaints about the hotel.”

In customer service and business: Businesses track complaints as a measurable category, often referring to “customer complaints,” “written complaints,” or “formal complaints.” The verb complains appears less often here, since business writing tends to describe outcomes and records rather than individual actions in the moment.

In medical settings: Healthcare documentation frequently uses “complains of” to record a patient’s reported symptom, such as “the patient complains of chest discomfort” or “the child complains of stomach pain every night.” Here, complains functions almost like a technical term for reporting a symptom, though it remains grammatically an ordinary verb.

In legal contexts: A formal complaint is also a specific legal document that begins certain types of lawsuits. In this context, “filing a complaint” refers to submitting an official document, and the plural, complaints, refers to multiple such filings.

Synonyms And Related Words

Word	Meaning	Difference From Complain/Complaint
Grumble	To complain in a low, muttering way	More casual and often quieter in tone
Protest	To object, often more formally or publicly	Suggests a stronger, more visible objection
Grievance	A formal complaint, especially in workplace or legal settings	More official and often written
Gripe	An informal complaint, often minor	Casual, sometimes humorous in tone

These words share meaning with complain and complaint but differ in formality, tone, or context. Complain and complaint remain the most neutral and widely used choices in both spoken and written English.
