If you have ever typed a sentence and stopped to wonder whether you should add an “s” at the end, you are not alone. Choosing between backward or backwards causes confusion for English learners and native speakers alike.
Because both forms refer to moving toward the rear or in a reverse direction, it is easy to see why people mix them up. In this guide, you will learn the exact differences between these two words, how to use them correctly in British and American English, and simple rules to help you
Both backward and backwards are correct, but their usage depends on whether you are using them as an adjective or an adverb, as well as whether you prefer American or British English. In American English, “backward” is commonly used for both roles. In British English, “backward” is preferred as an adjective (a backward step), while “backwards” is preferred as an adverb (walking backwards).
Which One Should You Use?
To choose the right word, look at its job in the sentence. If the word modifies a noun, you almost always want “backward.” If the word describes how an action is performed, you can choose based on your regional preference or standard stylistic conventions. Remember this core principle: “backward” is safe in almost all contexts globally, while “backwards” is primarily reserved for movement and direction.
Difference Table
| Feature | Backward | Backwards |
| Meaning | Moving or facing toward the rear; behind | Moving or facing toward the rear; behind |
| Usage | Adjective and Adverb | Adverb only |
| Grammar | Modifies nouns and verbs | Modifies verbs only |
| Context | Universal (US & UK) | Common in UK/Commonwealth; less common as adjectival in US |
| Frequency | Extremely high in all dialects | High in spoken English and British writing |
| Everyday Use | “Take a backward glance” | “He fell backwards” |
Meaning of Word 1
Definition and Grammar Role
Backward functions primarily as an adjective describing a noun, or as an adverb indicating direction. As an adjective, it describes something positioned behind, underdeveloped, or directed toward the past.
Everyday Situations
You will frequently see backward used when describing physical orientation or progress. For example, wearing a cap with the brim facing the rear is a backward baseball cap.
- She took a cautious backward step away from the ledge.
- The company’s outdated technology felt completely backward.
- He read the entire paragraph in backward order.
Meaning of Word 2
Definition and Grammar Role
Backwards functions strictly as an adverb. It indicates movement, looking, or counting in the reverse of the usual direction.
Regional Preferences
While North American English speakers freely use “backward” for direction, British English speakers strongly prefer “backwards” when describing physical movement.
- The toddler stumbled backwards into the soft cushions.
- Can you recite the alphabet backwards, starting from Z?
- The wind pushed the sailboat slowly backwards.
Why Do People Confuse These Words?
People confuse these terms because they share the exact same core definition and pronunciation. Many English adverbs add an “s” at the end to denote direction—such as towards, afterwards, and upwards. Because “backwards” follows this familiar pattern, language users naturally apply it to movement. However, because American English dropped the “s” suffix in many directional words over the centuries, both forms co-exist with overlapping functions.
Grammar Rule
The simplest way to separate these words is to check their grammatical function in the sentence. Adjectives describe things, while adverbs describe actions.
| Word Form | Grammatical Role | Example |
| Backward | Adjective (modifies noun) | A backward glance |
| Backward | Adverb (modifies verb) | Look backward |
| Backwards | Adverb only (modifies verb) | Walk backwards |
If the word sits right before a noun (like backward motion or backward country), you must use backward without the “s.”
Real-Life Examples
People
- The gymnast lost her balance and fell backwards onto the mat.
- She glanced backward to see if anyone was following her.
Technology
- The software update caused the system to revert to a backward compatibility mode.
- The script reads the text data backwards to decode the message.
Business
- Relying on manual spreadsheets is a backward step for a modern startup.
- The retail market experienced a backward trend during the third quarter.
Common Mistakes
❌ Incorrect: He walked backward into the room, tripping over the rug. (While acceptable in American English, British English prefers “backwards” for physical motion.)
✅ Correct: He walked backwards into the room, tripping over the rug.
❌ Incorrect: That policy is a huge step backwards for human rights. (Adjectives modifying nouns should drop the s.)
✅ Correct: That policy is a huge step backward for human rights.
Easy Memory Trick
Think of the letter S as standing for Steps. If you are taking physical steps in reverse, use the word with the “S” at the end (backwards). If there is no “step” involved, or if you are using the word right before a noun, drop the “S” and use backward.
Mini Quiz
Question 1: Which sentence uses the correct form?
- A) She took a backwards glance at her childhood home.
- B) She took a backward glance at her childhood home.
Answer: B. Because the word modifies the noun “glance,” the adjective form without the “s” is required.
Question 2: Fill in the blank: “The car rolled ________ down the steep hill.”
- A) backward
- B) backwards
Answer: Both A and B are correct, though “backwards” is more common in British English for physical movement, and “backward” is standard in American English.
Question 3: Which form is required before a noun?
- A) Backward
- B) Backwards
Answer: A. “Backward” is the only form that functions as an adjective before nouns.
Question 4: Can “backwards” be used as an adjective?
- A) Yes
- B) No
Answer: B. “Backwards” is strictly an adverb and cannot modify a noun directly.

Frequently Asked Questions (FAQs)
Are backward and backwards completely interchangeable?
Not always. While you can often use either as an adverb of direction, you cannot use backwards as an adjective before a noun. You must say “a backward glance,” never “a backwards glance.”
Is one spelling considered more correct globally?
Both spellings are fully correct in standard English dictionaries. However, regional preferences dictate usage, with American English favoring the shorter form and British English maintaining a clearer distinction between the two.
Which word should non-native English learners use?
If you want to keep things simple, use backward for everything. It functions correctly as both an adjective and an adverb in all major dialects of English.
Why does backwards have an “s” at the end?
The “s” developed historically from an old genitive adverbial ending in English, which was also used to form words like towards, afterwards, and sideways.
Can I use backwards at the beginning of a sentence?
Yes, as an adverb modifying the entire clause or action. For example: “Backwards and forwards, the pendulum swung rhythmically.”
Does Microsoft Word or Google Docs mark one as incorrect?
No. Modern spell checkers recognize both backward and backwards as valid English words, though some style guides prefer the version matching your target regional dialect.
Conclusion
Mastering the difference between backward and backwards comes down to understanding grammar roles and regional norms. Remember that backward can do double duty as both an adjective and an adverb, whereas backwards is strictly an adverb reserved for direction and movement.
Keep one simple rule in mind: When modifying a noun, always drop the s and use backward. With this quick rule, you can write with total confidence every time.
