See also: dead line



Wikipedia has an article on:


According to the Oxford English Dictionary, early usage refers simply to lines that do not move, such as one used in angling. Slightly later American usage refers to a boundary in a prison which prisoners must not cross. There is only indirect evidence that the sense of "due date" may be connected with this use of the term in prison camps during the American Civil War, when it referred to a physical line or boundary beyond which prisoners were shot.[1] In fact, the term is no longer found in print by the end of the 19th century, but it soon resurfaces in writing in 1917 as a printing term for a guideline on the bed of a printing press beyond which text will not print. Three years later, the term is found in print in the sense of "time limit" in the closely connected publishing industry, indicating the time after which material would not make it into a newspaper or periodical.[2]



deadline (plural deadlines)

  1. A date on or before which something must be completed.
    I must make this deadline or my boss will kill me!
  2. (archaic) A guideline marked on a plate for a printing press.
  3. (archaic) A line that does not move. (Can we add an example for this sense?)
  4. (archaic) A boundary around a prison, prisoners crossing which would be shot.

  1. (colloquial) deadline


The declension of this word is problematic. Joukahainen recommends the nalle-type declension, presumably based on the (English) spelling of the nominative of the word:

Inflection of deadline (Kotus type 8/nalle, no gradation)
nominative deadline deadlinet
genitive deadlinen deadlinejen
partitive deadlinea deadlineja
illative deadlineen deadlineihin
singular plural
nominative deadline deadlinet
accusative nom. deadline deadlinet
gen. deadlinen
genitive deadlinen deadlinejen
partitive deadlinea deadlineja
inessive deadlinessa deadlineissa
elative deadlinesta deadlineista
illative deadlineen deadlineihin
adessive deadlinella deadlineilla
ablative deadlinelta deadlineilta
allative deadlinelle deadlineille
essive deadlinena deadlineina
translative deadlineksi deadlineiksi
instructive deadlinein
abessive deadlinetta deadlineitta
comitative deadlineineen

On the other hand, the nalle-type declension does not fit the pronunciation, which in fact follows the risti-type declension (except in the nominative: /dedlain/), in other words, /dedlainin/, /dedlainia/, etc. in the genitive, partitive, etc. It's probably advisable to avoid using this word in writing and to use Finnish synonyms instead.
