Inputted or Input: Which One Is Correct?

I remember the first time this issue stopped me mid-sentence. I was writing an email late at night, moving fast, confident in my English, when suddenly I paused and thought, “Wait… should I write input or inputted?” 

It felt like a small thing, but the more I thought about it, the more confusing it became. I had seen input used as both a noun and a verb, butis inputted a word sounded correct too yet something about it didn’t feel right.

So I did what most of us do. I stopped writing and checked. That’s when I realized this isn’t just my problem; it’s something many writers struggle with, especially when English isn’t their first language. 

Many people pause when writing a sentence like “I inputted the data” or “I input the data.” Spellcheck may not flag either option, yet something still feels uncertain. That is exactly why so many users search for “inputted or input.”

 The confusion comes from how English handles verb tenses, especially with technical or business words that began as nouns.

The word input is everywhere today—used in emails, software, reports, education, and social media. But its past tense is debated. Some teachers say “input” is correct. Others accept “inputted.” Both forms appear online, which adds to the doubt.

This article solves that confusion clearly and simply. You will get a quick answer, learn where both forms came from, see how British and American English treat them, and understand which spelling to use based on your audience. 

We will also cover common mistakes, real-life examples, usage trends, and FAQs so you can write with confidence in any situation.

Inputted or Input – Quick Answer

Both “input” and “inputted” are correct past tense forms, but “input” is more widely accepted and preferred.

Examples

• ✅ I input the data yesterday. (preferred)
  
• ⚠️ I inputted the data yesterday. (acceptable but less common)
  

In professional, academic, and global writing, “input” is the safer choice.

The Origin of Inputted or Input

The word input started as a noun in the 18th century, meaning “what is put in.” Later, it became a verb, especially in technical and computing contexts.

When verbs come from nouns, English sometimes creates regular past tenses (like emailed or texted). That is how “inputted” appeared.

However, English also keeps some verbs unchanged in past tense (like cut, hit, put). Over time, “input” followed this pattern for many speakers.

This split history is why both forms exist today, but usage has shifted toward the simpler form.
