If you’ve ever paused while typing and wondered, “Is it untill or until?” you’re definitely not alone. It’s one of the most common spelling mix-ups in English, especially because many English words use double consonants. But when it comes to untill or until, only one spelling is correct.
The correct word is until.
“Untill” is a misspelling and is not accepted in standard English, whether you’re writing in British English or American English. Understanding why this mistake happens can help you avoid it in the future and improve your writing confidence.
In this guide, you’ll learn the correct spelling, grammar rules, pronunciation tips, examples, and the difference between similar forms so you never second-guess yourself again.
Is It Untill or Until?
The answer is simple: until is the correct spelling.
The word “untill” is incorrect because English dictionaries do not recognize it as a proper word. Although some people accidentally add an extra “l,” the standard spelling contains only one.
Correct:
- Until
- Wait until tomorrow.
- I stayed awake until midnight.
Incorrect:
- Untill
- I stayed awake untill midnight.
If you’re searching for “untill or until which is correct,” the correct choice is always until.
What Does “Until” Mean?
“Until” is a preposition and conjunction used to describe time. It means something continues up to a certain moment or event.
Examples:
- We waited until the rain stopped.
- She worked until 6 PM.
- Don’t leave until I arrive.
The word is commonly used in both spoken and written English, making it an essential part of everyday communication.
Why Do People Write “Untill”?
The confusion around untill or until spelling usually happens because of pronunciation patterns and spelling habits in English.
Many English words double the final consonant:
- Still
- Will
- Skill
Because of this, people sometimes assume “until” should also end with a double “l.” However, English spelling doesn’t always follow consistent rules, and “until” remains the correct form.
Another reason is typing speed. The extra “l” is often just a common typo rather than a true grammar misunderstanding.
Untill or Until UK: Is There a Difference?
No, there is no spelling difference between British English and American English for this word.
In both the UK and the US, the correct spelling is:
- Until
The incorrect form “untill” is not accepted in either variety of English.
This is important because some words do change spelling depending on the region:
- Colour vs Color
- Travelling vs Traveling
But “until” stays exactly the same everywhere.
How to Remember the Correct Spelling
If you struggle with untill or until, here are a few simple tricks to help you remember it.
1. Think of Similar Time Words
Words related to time often stay short and simple:
- Till
- Until
Neither word uses a double “l” at the beginning and end together.
2. Remember the Root Word
“Until” is closely related to “till,” which also uses one “l” at the start and two at the end naturally.
3. Use Spell Check Carefully
Modern spell-check tools usually catch “untill,” but relying entirely on software can create bad habits. Learning the correct spelling yourself improves long-term writing skills.

It’s worth noting that “till” is not a shortened form of “until.” In fact, “till” is actually the older word historically.
