The correct spelling is until. It is used as a preposition and a conjunction to indicate up to a particular time or before something happens. The word is common in everyday conversation, academic writing, business communication, and formal English.
The spelling untill is incorrect. It is a common misspelling caused by adding an extra “l” at the end of the word. Standard English dictionaries recognize only until as the correct spelling.
