Separated a group of deer? They will get the wind up (9)
I believe the answer is:
tornadoes
'separated a' is the definition.
I can't judge whether this definition defines the answer.
'group of deer? they will get the wind up' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'deer?' could be 'does' (I've seen this in other clues) and 'does' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
The remaining letters 'rna' 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?
(Another definition for tornadoes that I've seen is " Strong winds".)
