In addition to the definitions previously mentioned, "fair enough" can also be used to mean "fine; have it your way" (if you are trying to persuade somebody or show them a better way to get something done and they won't listen).- When can we use "Fair enough" and why we do not say "OK" or "Allright" ... ?
In Australia, "fair enough" is widely and commonly used to mean "OK, that's an acceptable explanation/plan/decision".In addition to the definitions previously mentioned, "fair enough" can also be used to mean "fine; have it your way" (if you are trying to persuade somebody or show them a better way to get something done and they won't listen).
On a slightly unrelated note, I've found that a lot of native speakers make this mistake: It's "all right", not "allright" and definitely not "alright". Same goes for "never mind" and "a lot" - all of them are made up of two words.
In Australia, "fair enough" is widely and commonly used to mean "OK, that's an acceptable explanation/plan/decision". In BrEng too.
As far as the objection to "alright", I don't agree, and nor do the following dictionaries:
Definition of alright adjective/adverb/exclamation from Cambridge Dictionary Online: Free English Dictionary and Thesaurus
Alright - Definition and More from the Free Merriam-Webster Dictionary
Alright | Define Alright at Dictionary.com
nor the Oxford English Dictionary (1998 edn):
"There is no logical reason for insisting on 'all right' as two words, when other single-word forms such as 'altogether' have long been accepted. Nevertheless, it is still considered by many people to be unacceptable in formal writing."
I think, however, there is a preference for 'all right' in most BrEng style guides. Here's the Guardian:
"'all right' is right, 'alright' is not all right (but note the Who song, much loved by generations of headline writers, was The Kids are Alright)"
and the Times:
"all right never alright".
Specifically, see the usage note on the latter.
