'Note also British English in future but American English in the future:
Please be more careful in future. (= from now on)
I'll have to be more carefure in the future.'
(Quoted from What You Need to Know about British & American English by George Davidson)
Is the phrase in future only used in British English?
What's the difference between in future and in the future?
By the way, is there any difference between in the future and for the future?
Thank you very much for your repoly.
"In the future" is used to describe when something will happen. "The concert will take place in the future."
"For the future" is used to describe preparations. "I'm saving that bottle of wine for the future."
If you replace those with "later", you can see that the "for" remains: "The concert will take place later." "I'm saving that bottle of wine for later."
In future you will leave your dog at home implies that on this (and perhaps previous occasions) you have brought your dog with you, but that the next time you come you should leave it at home.
In the future you will leave your dog at home is more of a prediction than a request.
In At some time in the future a hospital will be built here you cannot replace in the future by in future.
I would say that in future refers to some state of affairs that is to change from now on.
