Hairy place where weapons may be hidden? (6)
I believe the answer is:
armpit
But I can't explain it at all! Could you help me understand?
(Other definitions for armpit that I've seen before include "Depression under an upper limb" , "Where to put a crutch" , "(In anato my) the axilla" , "Bodily hollow" , "(In anatomy) the axilla" .)
