FAQ
Frequently Asked Questions
No, it is a noun. You 'meet a deadline', 'set a deadline', or 'work towards a deadline'. Using it as a verb (e.g., 'to deadline something') is considered non-standard business jargon.
It originated during the American Civil War, referring to a line within or around a prison camp. Prisoners who crossed it would be shot dead. The modern figurative meaning of a time limit emerged in the early 20th century, particularly in journalism.
While most common in professional and academic contexts, it is also used in everyday situations, e.g., deadlines for tax returns, library books, or competition entries.
They are often interchangeable. 'Due date' can sound slightly less severe and is common for recurring payments or assignments. 'Deadline' often carries a stronger sense of finality and consequence.
