When writing in English, you may wonder whether the correct word is input or imput. The correct spelling is input. It is a common English word used as both a noun and a verb, especially when talking about information entered into a computer, system, form, or process. Imput is a common spelling mistake and is not the standard English spelling.
Understanding the difference is useful for students, writers, office workers, and anyone who regularly uses computers or digital systems. In this guide, you will learn what input means, why people sometimes write imput, how to use the correct word in sentences, and how to remember its spelling easily.
Quick Answer
Input is the correct spelling. It can mean information entered into a system or the act of entering information. Imput is a misspelling and should not be used in standard English. For example: “Please input your password.” The past tense and past participle can also be input or inputted, depending on context.
Why Do People Confuse Input and Imput?
People often confuse input and imput because the pronunciation of input can make the n sound less noticeable in fast speech.
Another reason is that English spelling does not always perfectly match pronunciation. When people hear the word rather than see it written, they may incorrectly assume that it is spelled imput.
The important point is simple:
- Input = correct spelling
- Imput = incorrect spelling
Input
Input is the standard and correct English word.
It can function as a noun or a verb.
Input as a Noun
As a noun, input can mean information, data, advice, or ideas provided to a person or system.
Examples:
- Your input is important to us.

Input as a Verb

Imput
Imput is not the standard spelling of the English word.
If you mean information entered into a system or the act of entering information, use input, not imput.
For example:
❌ Please imput your information.
✅ Please input your information.
The incorrect form often appears because of pronunciation, typing mistakes, or confusion about the word’s spelling.
