Manly means of keeping a bit warm in bed? (5)
I believe the answer is:
beard
'manly means' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'keeping a bit warm in bed?' is the wordplay.
'keeping' is an insertion indicator (some letters kept inside).
'a bit warm in' becomes 'ar' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'ar' put within 'bed' is 'BEARD'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for beard that I've seen before include "hair extension" , "Whiskers" , "Hair on the chin" , "Vandyke, perhaps" , "Facial hair" .)
