I Swear EnglishVocabulary A–Z › Deadline

What does ‘Deadline’ mean?

Noun: a deadline · two deadlines · /ˈdedlaɪn/

A deadline is the date or time by which you must finish a task or submit something.

The deadline for sending in your story is 2 p.m. on Tuesday.

In this example, Tuesday is the final day, but the cutoff is 2 p.m., not midnight. If an instruction gives only a date, check the exact time and time zone instead of assuming you have until 11:59 p.m.

Words that go with deadline

  • Meet a deadline: finish on time. We finished early and met the deadline.
  • Miss a deadline: fail to finish in time. The editor could not use my story because I missed the deadline.
  • Set a deadline: decide the cutoff. Let’s set a deadline for choosing a name.
  • Extend a deadline: allow more time. The organiser extended the deadline by three days.
  • A tight deadline: little time is available. Two days to translate the booklet is a tight deadline.

A deadline is not necessarily impossible to change. Whether an extension or late submission is allowed depends on the person or organisation setting it.

By or until?

By gives the latest time for completion: Please finish the drawing by six. It can be finished earlier.

Until describes an activity or situation continuing to that time: I’ll work on the drawing until six. That sentence does not promise the drawing will be finished.

Deadline or dateline?

A deadline is a time limit. A dateline is the place, and often the date, printed at the start of a news report. You meet a deadline; you do not meet a dateline.

Why is it called a deadline?

Merriam-Webster records an older use for a boundary around a prison that prisoners risked being shot for crossing. The familiar time-limit meaning appeared in the early twentieth century. Treat “the point where a process dies” as a memory aid, not a literal account of the word’s history.

Watch: ‘Deadline’ explained

Original lesson by iswearenglish · Watch on YouTube

The transcript below preserves the original lesson. Its “becomes dead” explanation is a memory aid; the word history and the distinction between a deadline and an expiry date need their own context.

Original video transcript

D is for Deadline. Deadline, the last moment you can do something. OK. Normally an application will have a deadline. You must do something before a certain date. The deadline for this document is the thirty first of December. The limit. The deadline for you to hand in your homework is Monday. The deadline, the limit. The line at which, after that the whole thing becomes dead, you can't do it. You can have a deadline to file your taxes. OK. Or, erm... yes, a credit card has an expiry date. OK, to expire. The expiry date is the deadline for use of the card, you cannot use it after that date. So, D is for deadline, the last moment you can do something. The last moment to hand in work. The limit. So, thanks for watching and see you in another video. Bye.
