Is It “Infact” or “In Fact”?

The correct phrase is “in fact.”

Correct: In fact, I enjoyed the movie more than I expected.
Incorrect: Infact, I enjoyed the movie more than I expected.

“In fact” is a two-word phrase used to introduce additional information, emphasize a point, or clarify something. The single-word version “infact” is considered a spelling error in modern English dictionaries and grammar standards.

What Does “In Fact” Mean?

The phrase “in fact” means:

Actually
Indeed
As a matter of fact
To tell the truth
In reality

It’s often used to strengthen a statement or add surprising information.

Examples of “In Fact” in Sentences

He is very experienced. In fact, he has worked in the industry for 20 years.

These examples show how the phrase adds emphasis or clarification.

Why Do People Write “Infact”?

Many people combine the words because “in fact” is spoken quickly in conversation. When pronounced naturally, it can sound like one word.

This happens with other English expressions too, such as:

“a lot” becoming “alot”
“all right” becoming “alright”
“in to” confused with “into”

However, formal English grammar rules still require “in fact” to be written as two separate words.

Grammar Rule: “In Fact” Is Always Two Words

“In fact” functions as a phrase, not a standalone word. Because of this, the correct spelling always includes a space between “in” and “fact.”

Quick Grammar Tip

If you can replace the phrase with “actually” or “indeed,” then “in fact” is probably being used correctly.

Example:

In fact, the project finished early.
Actually, the project finished early.

Both versions make sense.
