Fourth or Forth – Quick Answer
Fourth is a number. It comes after third and before fifth. Order, position, and dates all call for it.
The second spelling means forward or onward. Movement and direction call for it. Set phrases also use it.
Simple examples:
- She finished in fourth place.
- Today is the fourth of March.
- He walked back and forth all night.
- The sun came forth from behind the clouds.
Easy trick: The word “fourth” has “four” inside it. Four is a number, so fourth is a number word. Mean a number? Write fourth. Mean “forward”? Choose the direction word.
The Origin of Fourth or Forth
Both words are very old, and both come from Old English.
Fourth grew from the Old English feowertha, built on feower, which means “four.” Speakers added “th” to show order. The same thing happened with “fifth” and “sixth.”
The direction word also began in Old English, where it meant “forward” or “away.” Linked to the word “fore,” it appears in “before” and “forward.” The number four has no part in its story.
So why do people mix them up? Old English spelling was not fixed, and words changed over many centuries. Today the two words sound alike. Writers hear one sound and guess the spelling.
Long ago, some writers even dropped the “u” and used this spelling for the number. Modern English settled the matter. Fourth names the number. The other names the direction.
British English vs American English Spelling
Here is the good news. British and American English agree on these two words. No regional rule exists, and the spelling stays the same in every country.
Geography is not the problem. Meaning is. Many spelling guides cover pairs like “color” and “colour,” but this pair works differently. Both countries use both words with identical spelling.
| Word | Meaning | British English | American English |
| Fourth | Number after third | fourth | fourth |
| Forth | Forward, onward | forth | forth |
| Fourth of July | US holiday | fourth of July | Fourth of July |
| Back and forth | To and fro | back and forth | back and forth |
Only the date style differs a little. Britons often write “4th July.” Americans write “July 4th” or “the Fourth of July.” The word itself never changes.
Which Spelling Should You Use?
Your choice depends on your meaning, not your audience.
For US readers:
Pick “fourth” for the number and the other spelling for forward motion. Capitalize “Fourth of July” because it names a holiday.
For UK and Commonwealth readers:
The rules match. “Fourth” shows order. The direction word shows movement and appears in phrases like “and so forth.”
For a global audience:
Follow one rule. Ask, “Do I mean a number?” A yes means fourth. A no means the other spelling.
Try a quick test. Swap the word for “forward.” If the sentence still works, use the direction word. A silly result means you need fourth.
Common Mistakes with Fourth or Forth
Writers repeat the same errors. Here are the most common ones.
Mistake 1: Using the direction word for a number
Wrong: She came in forth place.
Right: Use fourth for a number: She came in fourth place.
Mistake 2: Using “fourth” for direction
Wrong: He paced back and fourth.
Right: He paced back and forth.
Mistake 3: Writing “fourth coming”
Wrong: The book is fourth coming.
Right: Use forthcoming here: The book is forthcoming.
Mistake 4: Mixing up the direction word and “foreword”
A foreword is the short note at the start of a book. These two words share no link, even though they sound alike.
Mistake 5: Trusting spell check
Spell check will not flag these errors, since every one of these words is real. Always proofread your final draft by eye, and read each sentence aloud to catch a wrong word.
