Backward or Backwards? Which Is Correct?

🕓 Last updated on November 4, 2026

You are writing an email. You type “step backward” and stop. Should it be “step backwards”? You look at both and neither looks wrong.

You are not alone. Millions of people search “backward or backwards” every year. Both words look right, both appear in books and news, and both mean almost the same thing. That makes it hard to know which one is correct.

The good news is that this is an easy problem to solve. Neither word is a mistake. The difference comes down to where you live, who reads your writing, and how the word works in your sentence.

In this guide, you will get a quick answer first. Then you will learn where the words came from, how American and British English treat them, and which one to pick. You will also see common mistakes, real examples, usage patterns, and answers to common questions.

By the end, you will never pause over this word again.

Backward or Backwards   Quick Answer

Both are correct. Here is the simple rule:

• Backward is the safe choice. It works in American English as an adjective and an adverb. In British English it works as an adjective.
• Backwards is common in British English as an adverb.

Examples:

• She took a backward step. (adjective, US and UK)
• He fell backward. (adverb, US)
• He fell backwards. (adverb, UK)
• Say the alphabet backwards. (adverb, UK)
• Say the alphabet backward. (adverb, US)

Tip: If you are unsure, use “backward.” Nobody will call it wrong.

The Origin of Backward and Backwards

Both words are very old. They go back to Old and Middle English.

The word “backward” came from “aback” plus “-ward.” The ending “-ward” means “in the direction of.” You see it in “forward,” “toward,” and “upward.”

The ending “-wards” is also old. In Old English, “-weardes” was a form used to build adverbs. Over time, English speakers dropped and kept different endings in different places.

So why do two spellings exist? English never had one rule-maker. People used both forms for hundreds of years. Later, dictionaries tried to set rules. American dictionaries leaned toward the shorter forms, such as “backward,” “toward,” and “forward.” British writers kept the “s” forms more often, such as “backwards,” “towards,” and “afterwards.”

The two spellings are not a mistake. They are two paths of the same word.

British English vs American English Spelling

Here is how the two main styles treat these words.

American English prefers the shorter form. Most American writers use “backward” for everything. You will still see “backwards” in speech and some idioms, but it is less common.

British English uses both. “Backward” is the adjective: “a backward glance.” “Backwards” is the adverb: “walk backwards.” Commonwealth countries such as Australia, India, and Pakistan often follow the British pattern.

Use	American English	British English
Adjective (before a noun)	backward step	backward step
Adverb (after a verb)	step backward	step backwards
Common in speech	backward (backwards also heard)	backwards
Idiom: “bend over ___”	backward	backwards
Tech term: “___ compatible”	backward compatible	backward compatible
Style preference	shorter form	both, by role

The adjective is the one place where both styles agree. It is almost always “backward.”

Which Spelling Should You Use?

Pick based on your reader.

Writing for a US audience: Use “backward” every time. It matches American style guides and looks natural to your reader.

Writing for a UK or Commonwealth audience: Use “backward” before a noun and “backwards” after a verb. For example: “a backward glance” and “he looked backwards.”

Writing for a global audience: Use “backward.” It is understood everywhere and is never marked wrong.

Writing for school or work: Follow your style guide. If you have none, stay consistent. Do not use “backward” in one paragraph and “backwards” in the next, unless the grammar calls for it.

Writing SEO content: Match the spelling to your target country. A site for US readers should say “backward.” A site for UK readers should say “backwards” as an adverb.

Common Mistakes with Backward or Backwards

Here are errors people make often.

1. Using “backwards” before a noun.

• Wrong: a backwards step
• Right: a backward step

2. Mixing both in one text.

• Wrong: He leaned backward, then stepped backwards.
• Right: He leaned backward, then stepped backward. (Choose one.)

3. Changing a fixed phrase.

• “Backward compatible” is the standard tech term. “Backwards compatible” is also seen, but “backward” is safer.

4. Thinking one is a typo.

• Neither is a typo. Do not “fix” someone else’s choice unless their text must match a style guide.

5. Using “backwardly.”

• This word exists but is rare. In most cases, “backward” is cleaner.
