Hearty medic to transport idiots around, holding record (12)
I believe the answer is:
cardiologist
'hearty medic to transport' is the definition.
I can't judge whether this definition defines the answer.
'idiots around holding record' is the wordplay.
I cannot quite see how this works, but
'around' could be 'ca' (circa) and 'ca' is present in the answer.
'record' could be 'log' (logging is a kind of recording) and 'log' is present in the answer.
an anagram of 'idiots' is 'dioist' which is present in the remaining letters.
A single letter 'r' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for cardiologist that I've seen is " Specialist in heart disease".)
