If you want to write more naturally in English, learning how to use kind of correctly is essential. This phrase appears constantly in everyday conversation and informal writing, but many learners either overuse it or avoid it entirely. In this guide, you will learn exactly when and how to use kind of in sentences, how it changes the tone of your writing, and when you should choose a different phrase instead.
Quick Answer: What Does ‘kind of’ Mean?
Kind of has two main uses in English. First, it can mean a type or category of something (e.g., “What kind of music do you like?”). Second, and more commonly in casual writing, it works as a softener that means somewhat, slightly, or in a way (e.g., “I am kind of tired today”). This second use is what most learners need help with because it changes the strength of a statement.
In writing, kind of makes your sentences sound less direct and more conversational. It is perfect for emails to colleagues, personal notes, and informal blog posts. However, in formal academic or business writing, you should usually replace it with more precise words like somewhat, slightly, or rather.
Understanding the Two Meanings of ‘kind of’
1. Meaning: A Type or Category
When you use kind of to mean a category, it is followed by a noun. This use is neutral in tone and works in both formal and informal writing.
| Example | Meaning |
|---|---|
| What kind of book do you enjoy reading? | What type or genre of book? |
| This is a new kind of software. | A new category of software. |
| She grows a special kind of rose. | A specific variety of rose. |
2. Meaning: Somewhat or Slightly
This is the more challenging use. Here, kind of acts as an adverb that softens the adjective or verb that follows. It makes your statement less absolute and more tentative.
| Example | Meaning |
|---|---|
| I am kind of busy right now. | I am somewhat busy, but not completely. |
| That sounds kind of interesting. | It sounds slightly interesting, but I am not sure. |
| He kind of forgot about the meeting. | He almost forgot or partially forgot. |
Formal vs. Informal Tone with ‘kind of’
Knowing when to use kind of is just as important as knowing how to use it. The table below shows how the same idea changes depending on the tone you want.
| Informal (with kind of) | Formal (without kind of) | Context |
|---|---|---|
| I am kind of worried about the deadline. | I am somewhat concerned about the deadline. | Email to a colleague vs. report to a manager |
| This plan is kind of risky. | This plan carries a moderate level of risk. | Casual discussion vs. business presentation |
| She kind of agreed with the idea. | She expressed partial agreement with the idea. | Conversation vs. meeting minutes |
| I feel kind of tired today. | I feel slightly fatigued today. | Text to a friend vs. formal email |
