If you’ve ever paused while writing and wondered whether to use “what kind of” or “what kinds of,” you’re not alone. These two phrases look almost identical, but they serve slightly different purposes in English. Choosing the right one makes your writing sound more natural, accurate, and fluent. Whether you’re a student, professional, or English learner, understanding this difference can improve both your grammar and communication skills.
The good news is that the rule is straightforward once you understand how singular and plural nouns work. In this guide, you’ll learn the difference between what kind of and what kinds of, when to use each one, common mistakes to avoid, and practical examples you can apply in everyday conversations and writing.
Quick Answer
“What kind of” is used when asking about one type or category of something, while “what kinds of” is used when asking about multiple types or categories. The choice depends on whether you’re referring to a single category or several different categories.
Why People Confuse It
Many English learners mix up these expressions because both ask about categories or types. The only visible difference is the addition of “s” in “kinds,” making it seem like a minor change.
The confusion also increases because both phrases can sometimes appear before plural nouns.
For example:
- What kind of books do you enjoy?
- What kinds of books do you enjoy?
Both sentences are grammatically correct, but they ask slightly different questions.
First Word: What Kind of
“What kind of” refers to one particular type or category. Even if the noun following it is plural, the speaker is asking about a single general classification.
Structure
What kind of + noun + verb
Examples
- What kind of music do you like?
- What kind of books do you read?
- What kind of job are you looking for?
- What kind of phone do you have?
- What kind of weather do you prefer?
In these examples, the speaker expects one general answer rather than several categories.
Second Word: What Kinds of
“What kinds of” refers to multiple types or categories. It invites the listener to mention several different groups or varieties.
Structure
What kinds of + plural noun + verb
Examples
- What kinds of movies do you enjoy?
- What kinds of fruits grow here?
- What kinds of problems have you faced?
- What kinds of sports are popular in your country?
- What kinds of skills should I learn?
Here, the speaker expects more than one category in the answer.
