Many English learners, students, and even native speakers often wonder whether the correct spelling is until or untill. Since the two spellings differ by only one extra “l”, they are easy to confuse. However, only one spelling is accepted in standard English. The correct spelling is until, while untill is a common spelling mistake.
The word until is one of the most frequently used words in English. It appears in conversations, emails, text messages, school assignments, business documents, contracts, books, and everyday communication. It is used to describe the time when something continues or ends. The good news is that both American English and British English use the same spelling: until.
Many people misspell until because they assume the word should end with two “l” letters, similar to words like still or fill. However, until always ends with a single “l.” Understanding its meaning, grammar, pronunciation, examples, history, and memory tricks will help you remember the correct spelling every time.
