Post result of this interruption to journey (4-3)
I believe the answer is:
stop-off
'of this interruption to journey' is the definition.
The definition suggests a singular noun which matches the answer.
'post' is the wordplay.
I cannot really understand how this works, but
an anagram of 'post' is 'stop' which is within the answer.
The remaining letters 'off' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'result' acts as a link.
(Another definition for stop-off that I've seen is " Break in journey".)
