Until is the correct spelling. Untill is a common misspelling and does not appear in standard dictionaries. The word until has one L in American, British, Australian, and Canadian English, whether it works as a preposition or a conjunction.
The confusion is understandable. Many English words end in a double L, such as spill, drill, and install, so untill can look right at a glance. This guide explains the meaning of until, how to use it correctly, how it differs from till, and why the one-L spelling is the only safe choice for school, work, and publishing. Clear examples and memory tricks are included.

Meaning Of Until
Until shows how long something continues or when it stops. It points to the moment a situation ends or a new one begins.
- Duration: “We stayed in Lahore until Sunday.”
- Condition for change: “Keep stirring until the sauce thickens.”
Etymology
Until combines an Old Norse element meaning “up to” with the older word till. It entered English in the Middle Ages, and its spelling has had one L ever since.
Meaning Of Untill
Untill has no meaning because it is not a recognized English word. It appears only as a typing or spelling mistake.
If you see it in a draft, replace it with until. The error does not change meaning, but it can make writing look careless.
Until Or Untill Key Differences

Until Or Untill Which One Is Correct

Common Mistakes
1. Adding An Extra L
Writers add a second L because many words end in double L.
- Incorrect: untill
- Correct: until
2. Assuming Both Spellings Are Acceptable
Only one spelling is valid. A word processor that does not flag untill may be set to ignore certain errors, so do not treat silence as approval.
3. Copying Online Errors
Social media posts and messages often contain untill. Seeing a mistake repeatedly does not make it correct.
4. Confusing Familiar Patterns
Words like until, install, and enroll look similar, but their spellings follow different histories. Until has a single L because its second part, til, is spelled that way in the dictionary.
Until Or Untill Pronunciation Guide
IPA
Until is commonly written /ənˈtɪl/ in IPA. Some speakers use /ʌnˈtɪl/. Pronunciation is the same in American and British English for most speakers.
Syllables
Until has two syllables: un-til.
Stress
The stress falls on the second syllable: un-TIL.
Common Pronunciation Mistakes
- Stressing the first syllable (UN-til).
- Adding an extra syllable.
- Saying the second part with a long vowel, as in “tile.”
The double L in untill has no effect on pronunciation, which is another reason the misspelling is unnecessary.
Etymology And Word Origin
Until is built from two parts. The first, un-, is not the English negative prefix but comes from an Old Norse word meaning “up to.” The second, til, is the older word till.
Till itself is the older form and is not a shortened version of until. Both words ended up with the same meaning in modern English. Dictionaries record the single-L spelling throughout the word’s history, so untill has no historical basis.

Related Words And Confused Terms
Till
Till is a standard synonym of until and is slightly more informal. It can also mean to cultivate land or a cash drawer, so context decides which meaning applies.
By
By marks a deadline. “Finish by noon” means at or before noon. “Work until noon” means keep working up to noon.
Before
Before refers to an earlier time without stressing continuation. “Leave before noon” is not the same as “stay until noon.”
Unless
Unless introduces a condition meaning “if not.” It is not a time word. “I will go unless it rains” is not the same as “I will go until it rains.”
As Long As
As long as means “on the condition that” or “for the duration that.” “Stay as long as you like” focuses on permission or duration, not an end point.
Expert Language Insight
Language specialists generally treat till and until as equal in meaning, with until slightly more common in formal prose. Some style guides prefer until in formal writing, while many dictionaries note that till is older and fully standard. Neither form is wrong. The only fixed point is that the double L spelling has no standing.
Advanced Usage Tips
Use Until To Show An Ending Point
Choose until when the focus is on when something stops: “The sale runs until Sunday.”
Choose Until In Formal Writing
Reports, essays, and official notices read more smoothly with until than with till or ’til.
Avoid Repeating Until Unnecessarily
Repeated use of until in one paragraph can sound heavy. Vary it with “up to,” “through,” or “before” when the meaning allows.
Match The Time Reference
Make sure the verbs agree with the time frame. Say “She will wait until he arrives,” not “She will wait until he will arrive.”
Easy Memory Tricks
1. Remember That Dictionaries Use One
Every standard dictionary lists until with one L. When unsure, think of the entry, not the double L in other words.
2. Think Of The Ending
Until ends with a single L, just as the word “until” itself marks a single end point.
3. Let Spell Check Confirm It
Spell check will underline untill. Treat that underline as a reliable correction.
4. Read Quality English
Edited books, newspapers, and academic journals use the correct form. Regular reading strengthens spelling memory.
Why Do People Write Untill
Double Letter Patterns
Many English words end in LL, so writers apply that pattern automatically.
Fast Typing
