Forsure vs. For Sure – Which is Correct?
For sure is the standard English phrase, while forsure is generally a misspelling. Use “for sure” as two separate words when you mean certainly, definitely, or without doubt. It is common in conversation and informal writing, but alternatives such as “certainly” or “definitely” may sound more professional in formal contexts.
For another commonly confused spelling, compare Definately vs. Definitely when choosing a formal alternative.
Forsure or For Sure – Which is Correct?
For sure is the correct standard spelling. It is an informal fixed phrase meaning “certainly,” “definitely,” or “without doubt.” Forsure, written as one word, is generally a spelling error caused by the way the phrase sounds in fast speech.
Although people may use forsure in usernames, text messages, branding, or other casual online contexts, it is not the conventional form in edited American English. In schoolwork, business writing, applications, and professional communication, always write for sure as two words.
The Best Trick to Remember the Difference
Use the “for certainty” test: if the phrase means “for certain,” keep the two words separate—for sure. You can also remember that sure is an adjective after the preposition for, just as in phrases such as for good and for now. Never combine the words in standard writing.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| for sure | Adverbial phrase | Certainly or definitely | “I will be there for sure.” |
| forsure | Nonstandard spelling | Usually an incorrect closed form of “for sure” | Use “for sure” instead. |
How to Use For Sure
For sure is an adverbial phrase used to express certainty, agreement, or strong confidence. It is especially common in spoken English and informal writing. Depending on its position, it can modify an entire statement, emphasize a verb, or respond independently to a question.
At the beginning of a sentence, for sure can introduce a confident opinion. At the end, it often emphasizes certainty. It can also stand alone as an informal affirmative response. In highly formal writing, certainly, definitely, or undoubtedly may be more appropriate.
Example 1: “For sure, we need more time to complete the project.”
Example 2: “She is coming to the celebration for sure.”
Example 3: “Are you interested in joining us?” “For sure!”
Etymology of the phrase for sure
The phrase combines the preposition for with the adjective sure. The word sure comes through Old French from Latin securus, meaning “free from care” or “certain.” The expression for sure developed as an emphatic way to indicate certainty and has become especially frequent in conversational English.
