Different From vs Different Than vs Different To

Different From vs Different Than vs Different To: The Short Answer

“Different from” is the safest choice everywhere in English. Merriam-Webster’s usage guide says plainly: “from is the word most of the usage guides want you to use, especially in the US.” That said, none of the three is “wrong.” “Different than” is standard in American English, especially before a clause, and “different to” is common in British English. If you want one rule to memorize: use “different from” when in doubt, and you will never go wrong.

This guide explains all three forms — which one to use, where, and why — with examples, so you can choose confidently instead of guessing.

“Different From” — The Universal Safe Choice

“Different from” is the oldest of the three forms, with evidence of use going back to the 15th century, and it remains the most common worldwide. It is standard in both British and American English, which makes it the form to default to in any situation: formal writing, exams, business emails, everyday speech.

Merriam-Webster’s Pocket Guide to English Usage notes that “different from” works best when it is followed by a noun or a pronoun. That covers the great majority of real-world sentences:

• “My new laptop is very different from my old one.” (noun)
• “Her view is so different from his.” (pronoun)
• “This restaurant is different from the one we tried last week.” (noun phrase)

If you replaced “from” with “than” or “to” in any of these, many readers would wince — but “different from” pleases everyone. When a teacher, an editor, or a style guide corrects you, they are almost always correcting toward “different from.”

One more thing “different from” handles gracefully: comparisons with clauses, when the clause is introduced to act as a noun. “The campus is different from how it was twenty years ago” is perfectly natural, because “how it was” functions as a noun-like unit.

“Different Than” — Standard in American English

Here is where most of the confusion lives. “Different than” has been condemned by critics since the 18th century — yet it has been used by some of the best-known writers in English literature since the 17th century, and dictionaries call it standard. Merriam-Webster’s dictionary usage note puts it directly: “different than” is “standard and is even recommended in many handbooks when followed by a clause, because insisting on from in such instances often produces clumsy or wordy formulations.”

The key pattern: “different than” shines before a clause — a full statement with a verb in it. Compare:

• “The situation is different than it was last year.” (clause: “it was last year”)
• “She looks little different now than we remember her from our school days.” (clause: “we remember her…”)
• “We expected a different result than to be left penniless.” (clause-like infinitive phrase)

Forcing “from” into these sentences often sounds awkward: “different from it was last year” trips the tongue. That is why “different than” survives and thrives in American English — it solves a real sentence problem.

Two important limits. First, “different than” is much more common in American English than in British English, where it can still raise eyebrows. Second, before a simple noun or pronoun, “different than” sounds off to most ears: “different than my old one” is the sentence most likely to get corrected. So the working rule is: “different than” for clauses, “different from” for nouns and pronouns.

“Different To” — The British Option

“Different to” is the third form, and it is mostly a British English habit. Like the other two, it has been in use for hundreds of years — Merriam-Webster cites examples back to 1530 (“The houres of the planettes ben dyfferent to them of clockes”). Today, “different to” is common and unremarkable in British speech and writing:

• “This flat is quite different to the one I lived in before.”
• “Her approach is different to mine.”

In American English, though, “different to” is rare and will often be marked as an error by American readers and editors. Some British style guides also prefer “from,” but “different to” does not sound wrong to British ears the way it can to American ones. The practical takeaway: if you write for a British audience, “different to” is acceptable; if you write for an American or international audience, avoid it.

Quick Rules to Get It Right

If you want a cheat sheet, here it is:

1. Default to “different from.” It is correct everywhere — British, American, formal, informal. When you are unsure, “from” is never the wrong answer.
2. Use “different than” before a clause in American English. “The weather is different than it was yesterday” reads naturally; “different from it was yesterday” does not.
3. Reserve “different to” for British English. It is normal in the UK but rare and often flagged in the US.
4. Never use “different than” before a plain noun or pronoun. “Different than my brother” sounds wrong to almost everyone; write “different from my brother.”
5. In formal or exam writing, use “different from” exclusively. Examiners and editors expect it, and it is never penalized.

Common Mistakes to Avoid

The most frequent error is using “different than” with a noun: “This phone is different than my old one.” Change it to “different from my old one” and the sentence is instantly safer.

Another mistake is the reverse — hypercorrection. Some writers, told that “different than” is wrong, start avoiding it even where it helps: “The outcome was different from we had hoped” is clumsy. “Different than we had hoped” is the smoother, standard American choice.

Finally, do not mix the forms in one piece of writing. Pick the form that fits your audience — “from” for safety, “than” for American clauses, “to” for British informality — and stay consistent.
