Wonder what's in drawer (3)
I believe the answer is:
awe
'wonder' is the definition.
(awe is a kind of wonder)
'in drawer' is the wordplay.
'in' says the answer is hidden in the clue.
'AWE' is hidden in the letters of 'drawer'.
'what's' acts as a link.
(Other definitions for awe that I've seen before include "Great wonder" , "Wonder, reverence" , "Wondrous fear" , "Feeling of reverence" , "Fear/wonder feeling" .)
