Scottish expression a non-enthusiast couldn't give two of (5)
I believe the answer is:
hoots
'scottish expression a non-enthusiast couldn't' is the definition.
I can't judge whether this definition defines the answer.
'two of' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is found within the answer.
The remaining letters 'hots' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'give' acts as a link.
Can you help me to learn more?
(Other definitions for hoots that I've seen before include "Roars with laughter" , "Sounds of the owl" , "Owl noises" , "provoking expression of irritation" , "Loud raucous cries of an owl" .)
