Short distance runner claiming Greek character's too passionate (7)
I believe the answer is:
overhot
'short distance' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'runner claiming greek character's too passionate' is the wordplay.
I cannot quite understand how this works, but
'runner' could be 'r' (abbreviation) and 'r' is present in the answer.
'passionate' could be 'hot' (associated in meaning) and 'hot' is present in the answer.
'character' could be 'v' and 'v' is located in the answer.
The remaining letters 'oe' 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?
