Clothing covering Dougal's rear? (4)
I believe the answer is:
kilt
'clothing covering dougal's rear?' is the definition.
I can't judge whether this defines the answer.
'clothing covering dougal's rear?' is the wordplay.
'clothing' becomes 'kit' (I've seen this in other clues).
'covering' is an insertion indicator.
'rear?' indicates one should take the final letters (I've seen 'rear' mean this (the back of the word)).
The last letter of 'dougal' is 'l'.
'kit' enclosing 'l' is 'KILT'.
(Other definitions for kilt that I've seen before include "Scotsman's garb" , "Knee-length tartan garment" , "Checked menswear" , "Part of Highland dress" , "Bone; circle line" .)
