what's the difference between three-month journey/ three months' journey?
I think that the first indicates a journey of three months, the second indicates three months of journey (not all in one time). Am I right?
Hi, HocusPocus93. This is just a guess on my part, so don't go round thinking it's necessarily correct!
I think that three months' journey (not a three months' journey, which I believe is incorrect), means three months' worth of journeying. It's a way of showing that the speaker is measuring the action of journeying in units of time.
Another example I can think of is when someone says to you, the pub is only 5 minutes' walk from here, which to my way of thinking implies that the speaker is measuring the distance in terms of the time that it would take me to walk down to the pub.
Three-month-long journey, on the other hand, is a phrase consisting of an adjective and a noun.
