Main high jumper prone to interrupt fellows roughly (6,4)
I believe the answer is:
flying fish
'main high jumper' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'prone to interrupt fellows roughly' is the wordplay.
I cannot really understand how this works, but
'prone' could be 'lying' (I've seen this before) and 'lying' is located in the answer.
'fellows' could be 'ff' and 'ff' is present in the remaining letters.
The remaining letters 'ish' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for flying fish that I've seen before include "Gliding sea creature" , "Exotic angling target" .)
