Across is the correct spelling. Accross, with two c’s, is always a misspelling and never appears in standard English. The confusion happens because the word sounds like it should double the consonant, the way “accept” or “accident” do, but “across” simply doesn’t follow that pattern.
Quick Answer: Across Is Correct, Accross Is Not
| Spelling | Status | |
|---|---|---|
| ✅ | across | Correct in all forms of English |
| ❌ | accross | Misspelling, not a recognized word |
- Correct: She walked across the street to catch the bus.
- Incorrect: She walked accross the street to catch the bus.
The only difference between the two is that extra “c.” There’s no hidden meaning, no regional variant, and no context where “accross” is acceptable — it’s simply a typo that has become common enough to search for.
What Does Across Mean?
At its core, across describes movement or position from one side of something to the other. If you can picture two points with space between them, “across” is usually the word connecting them.
The most common meaning is movement from one side to the opposite side:
The dog ran across the yard to greet its owner.
A second common meaning is position on the opposite side:
The pharmacy is across from the coffee shop.
A third meaning describes something that extends or exists throughout an area, group, or system:
The new policy will apply across every department.
Less commonly, “across” appears in measurements, describing the width of something:
The table is about four feet across.
And in crossword puzzles, “across” is used as a noun or label for horizontal answers — a niche use most readers won’t need, but worth knowing if the word ever shows up that way.
Where Does the Word “Across” Come From?
“Across” is built from the prefix a- and the word cross, so it literally suggests “in the form of a cross” or “crosswise.” That combination is the reason the correct spelling has only one c — it comes from “cross,” which has one c, not from any word with a doubled consonant.
The word traces back to Middle English, where it developed from an Old French phrase meaning “in the shape of a cross” or “on a cross.” Over time, its meaning shifted from describing a crossed position to describing movement from one side of something to the other — the sense we use today. English also had a few competing regional forms of this word centuries ago, but the version that survived and became standard is the one spelled with a single c: across.
Similar spelling confusion happens with really vs. realy, where pronunciation causes writers to leave out a necessary letter.
How Many Syllables Does Across Have?
Across has two syllables: a-cross. The stress falls on the second syllable, so it’s pronounced roughly “uh-KRAWSS,” not “AY-cross” or “AH-cross.”
How to Pronounce Across Correctly
In everyday American English, “across” is pronounced with a soft first syllable (“uh”) and a stronger second syllable that rhymes with “boss” or “loss.” British pronunciation is very similar, with only a slight difference in how the vowel in the second syllable is shaped — a small accent variation rather than a different word or spelling. Either way, both syllables land on the same letters: a-c-r-o-s-s, never a-c-c-r-o-s-s.
What Part of Speech Is Across?
“Across” most often functions as a preposition or an adverb, depending on the sentence.
Across as a Preposition
As a preposition, “across” connects to a noun and shows movement or position relative to it.
We paddled across the lake before sunset.
Here, “across” links directly to “the lake,” telling you where the movement happened.
Across as an Adverb
As an adverb, “across” stands on its own without a following noun, often describing movement toward a general direction.
He looked over and waved across.
In this case, there’s no object directly after “across” — it simply describes the direction of the wave.
“Across” doesn’t have separate noun, verb, or adjective forms in everyday writing. It stays the same word regardless of tense or number, which makes it easier to use correctly once you know its two main jobs.
Why Do People Misspell Across as “Accross”?
The mistake usually comes down to two things: sound and habit.
First, when “across” is spoken quickly, the “cr” sound in the middle can feel like it needs extra weight, which nudges some writers toward doubling the c. Second, English really does double consonants in many similar-sounding words, like “accident,” “accept,” and “according.” That pattern is common enough that people unconsciously apply it here, even though “across” doesn’t follow it.
The simplest way to avoid the mistake is to remember that “across” is built from cross, a word that already has one c. Since “across” doesn’t add a new c, it keeps the single c from “cross” and only adds the letter a at the front.
Similar word confusion happens with emersion vs. immersion, where opposing meanings are often mixed up.
Is “Accros” (One C) Also Wrong?
Yes. Accros, with a single c and a single s, is also an incorrect spelling of “across.” It’s less common than “accross,” but it shows up for the same reason: the word is being spelled by ear instead of by its root, “cross.”
Here’s a quick summary of the misspellings people search for most:
| Misspelling | Why It’s Wrong |
|---|---|
| accross | Adds an extra c that “cross” doesn’t have |
| accros | Drops one s from the correct ending |
| acros | Drops one letter from each part of the word |
| acrosss | Adds an extra s at the end by mistake |
All of these are typos or phonetic guesses. Only across — one c, two s’s — is correct.
Is There a British vs American Spelling of Across?
No. “Across” is spelled the same way in British English and American English. There’s no regional variant, no alternate accepted form, and no exception for either dialect. The only differences between the two regions involve pronunciation, not spelling — a small shift in how the vowel sound is shaped, not a different set of letters.
This puts “across” in a different category from word pairs like “color/colour” or “realize/realise,” where spelling genuinely changes by region. With “across,” the spelling stays fixed everywhere English is written.
Across in a Sentence: Grammar and Usage
Using “across” correctly mostly comes down to recognizing what it’s connecting.
- Correct: They built a bridge across the river. Incorrect: They built a bridge accross the river. Explanation: “Accross” is never correct, regardless of the sentence structure around it.
- Correct: The news spread across social media within hours. Incorrect: The news spread across accross social media within hours. Explanation: Only one form of the word should ever appear — never both, and never the misspelled version alone.
- Correct: Our team is spread across three time zones. Incorrect: Our team is spread throughout across three time zones. Explanation: Choose one preposition; combining “throughout” and “across” in the same phrase creates redundancy, not emphasis.
Example Sentences With Across
- Everyday English: She waved at me from across the street.
- Academic writing: The researchers observed similar patterns across all three test groups.
- Workplace communication: Please share this update across the whole team by Friday.
- Online forms: Your information will be saved across all linked devices.
- Formal writing: The committee’s findings apply across every regional office.
Common Phrases With Across
“Across” also appears in a few fixed phrasal expressions that go beyond its literal, spatial meaning.
Come across means to give a certain impression or to be perceived a particular way.
He came across as confident during the interview.
Get something across means to successfully communicate an idea so others understand it.
The teacher used examples to get the concept across to her students.
These phrases use “across” figuratively, but the spelling rule doesn’t change — it’s still one c, never two.
Across vs Through vs Over: Key Differences
These three words all describe movement between two points, but they depend on the shape of the space involved.
| Word | Best used for | Example |
|---|---|---|
| Across | Flat, open, two-dimensional spaces or surfaces | She walked across the field. |
| Through | Enclosed, three-dimensional spaces you move inside of | She walked through the forest. |
| Over | Something with height that you go above or beyond | She climbed over the fence. |
A simple way to remember it: use “across” for things you’d describe as being on (on the ice, on the road), use “through” for things you’d describe as being in (in the tunnel, in the crowd), and use “over” when height or elevation is the main idea.
They’re not fully interchangeable. Saying “she walked through the field” changes the image to something enclosed or dense, like tall grass, while “she walked across the field” simply describes crossing open ground.
Across vs Throughout: What’s the Difference?
Across usually describes movement or distribution from one side of something to the other. Throughout describes something present in every part of a place or during an entire period of time.
The signal is weak across the north side of the building. (a specific area or direction) The signal was weak throughout the entire meeting. (the whole duration or the whole space, without emphasis on direction)
They overlap when describing something spread over an area — “problems across the company” and “problems throughout the company” are both acceptable — but “throughout” leans more formal and emphasizes completeness, while “across” leans more neutral and emphasizes range or extent.
Synonyms and Similar Words to Across
Depending on context, these words can substitute for “across”:
- over
- through
- throughout
- past
- beyond
- opposite
- on the other side of
Choose based on meaning: “over” and “through” work for physical movement, “throughout” and “over” work for describing extent, and “opposite” or “on the other side of” work when describing position rather than movement.
Memory Tricks to Never Misspell Across Again
These tips are simple learning aids, not official grammar rules:
- Remember that across contains cross, and “cross” only has one c.
- Think of it as a + cross = across — nothing extra gets added in the middle.
- Say it slowly in your head as “a-CROSS,” matching the two syllables to the two parts of the word.
- If your spell-checker underlines “accross,” trust it. Every major spell-checker flags this specific misspelling.

Frequently Asked Questions
Is “accross” ever correct in any dialect of English?
No. “Accross” is not accepted in any dialect, formal style, or region. It’s a misspelling everywhere the word “across” is used, including both British and American English.
What is the correct spelling of across — one C or two?
The correct spelling has one c: a-c-r-o-s-s. It comes from the word “cross,” which also has a single c.
Why does across sound like it has a double C?
When spoken at normal speed, the “cr” sound can feel emphasized, which leads some writers to assume a doubled letter is needed. Many similar-sounding words, like “accept” or “according,” do double their consonant, so the habit carries over even though “across” doesn’t follow that pattern.
Is “acrosss” (with three s’s) a typo, and what’s correct?
Yes, that’s a typo. The correct spelling ends in exactly two s’s: across.
Can “across” be used as a noun?
Only in one narrow context: crossword puzzles, where “across” labels a horizontal answer. In everyday writing, it functions as a preposition or adverb, not a noun.
What’s the difference between across and cross?
“Cross” can function as a verb (“to cross the street”), a noun (“a cross on the map”), or an adjective (“a cross word”). “Across” is a preposition or adverb that describes movement or position relative to something, as in “walk across the street.”
Is it “across from” or “across of”?
“Across from” is correct. “Across of” is not standard English. Use “across from” to describe something positioned on the opposite side.
Does British English spell across differently than American English?
No. The spelling is identical in both varieties. Only minor pronunciation differences exist between the two.
What’s the difference between across and throughout?
“Across” usually emphasizes movement or range from one side to another, while “throughout” emphasizes complete coverage of a space or an entire span of time. They sometimes overlap, but “throughout” carries a more formal, all-encompassing tone.
Is “accros” the same mistake as “accross”?
They’re different misspellings of the same word. “Accros” drops a letter from the correct ending, while “accross” adds an extra c. Neither is acceptable in standard writing.
How do you use across in a sentence about time?
“Across” isn’t the strongest choice for time-based sentences; “throughout” or “over” usually work better. Still, it appears in phrases like “across the decades” or “across recent years” to describe something spanning a period broadly.
What does “come across” mean as a phrasal expression?
“Come across” describes the impression someone gives, as in “He came across as nervous during the presentation.” It’s a figurative use of “across” and doesn’t change the spelling rule.
The Bottom Line
Across is the only correct spelling — accross, accros, and acrosss are all mistakes that don’t belong in standard writing. The easiest way to remember it is to picture the word “cross” hiding inside “across,” since neither one needs a doubled c. Once that connection sticks, the spelling stops being something you have to think about.
