I understand what the sentence The house is a full day’s journey from here means, but I’m wondering what day’s is short for in this expression. It doesn’t match any pattern I know.

A couple of examples:

  • He’s = he is
  • Let’s = let us
  • Mary’s car = the car belongs to Mary
  • Day’s = it sounds to me like something belongs to a day and this is what I don’t understand. Shouldn’t it be The house is a full day of journey from here instead?

    This is not in fact true, though a belief that it was brought about a short-lived blossoming of phrases like 'Nick his dog' in the 1500s and onwards Commented Jan 9, 2014 at 10:20

    "The house is a full day its journey from here." That just doesn't make sense to me though. What on earth is "its" doing in there?

    And then it would be "Mary'r car".

    @Bleeding Fingers: "Mary his car" or "Mary her car"?

The fourth example is the correct interpretation of day's, but with two things to keep in mind.

First, in your conclusion you flipped the words around incorrectly*; the journey "belongs to" the day, not the other way around. You could re-write the sentence as:

The house is a journey of a full day from here.

Second, while the journey is "of a day," this does not necessarily mean the day "owns" or "possesses" the journey; grammatically, time periods are simply treated as possessive.

* "A full day of journey" would actually work, but that would make "of journey" a subordinate clause rather than the day belonging to the journey; though, as WS2 brought out in the comments, this should actually be "A full day of journeying".

    But a 'full day's journey' would be the normal expression.

  • @WS2 You are right, in English, it would. Just like "Phil's ball" is more normal than "The ball of Phil" even though both are grammatically correct.

    And, of course, don't forget plurals, e.g. "The coast is two full days' journey from here" Commented Jan 8, 2014 at 13:34
  • Thanks for your answer! To me "full day's journey", "a full day of journey", "a journey of a full day", "a journey that takes a full day" sound correct.

    @Jim They would all be correct grammar except for 'a full day of journey'. That would need to be 'a full day of journeying'. But you can't really beat 'a full day's journey' for correctness and succinctness.

It's called a "transferred epithet"- the possessive case is incidental, as in...

I had a good night's sleep: The good sleep was mine to enjoy, but it is attributed to the night it happened.

He put in a honest day's work: The quality or extent of work belonged to the doer, but it is attributed to the day.

  • Interesting. I did not know the possessive was incidental...

  • This should be the accepted answer. You get my upvote. Also, here are a couple of links to definitions of hypallage and transferred epithet.

The 's on the day's is possesive in your case - but see @Simha's answer

More time examples

  • Three months' experience
  • One month's experience
  • Today's appointment
  • In two days' time
  • A year's worth of magazines

It means something that belongs or is associated to a given day.

  • That particular day's event.
  • It happened on this year's second month's third day's eleventh hour
  • Your possessive in the second example does not match the question's possessive

The journey does indeed belong to the day in the same way that the wages belong to the day in the sentence, "This will cost a full day's wages." There is no other word in the original sentence that day's could modify. I think it is just a simple possessive modifier like the example: "The satellite will follow the moon's rotation." It will follow the rotation of the moon.

"The house is a full day’s journey from here." It is a journey of a full day from here.


Your "full day of journey" proposal is correct. Think of the possessive apostrophe meaning "of" (in the sense of belonging), and you won't go far wrong.

If it still sounds strange, it's because people are using flowery language: in place of "a day's journey" you might imagine a flowery writer using the phrase, "a journey so long, that it was servant to the day".
