It's coming true, maybe, after a bit of fun (6)
I believe the answer is:
future
'it's coming' is the definition.
(similar in meaning)
'true maybe after a bit of fun' is the wordplay.
I cannot quite see how this works, but
an anagram of 'true' is 'ture' which is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for future that I've seen before include "Time that is 4 down" , "Verb tense; to come" , "What's yet to come" , "What is yet to pass" , "Time yet to come" .)
