Question being embarrassed by present getting returned (6)
I believe the answer is:
wonder
'question' is the definition.
(I know that question can be written as wonder)
'embarrassed by present getting returned' is the wordplay.
'embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'by' is a charade indicator (letters next to each other).
'present' becomes 'now' (both can mean the current period).
'getting returned' says the letters should be written in reverse.
'red'+'now'='rednow'
'rednow' back-to-front is 'WONDER'.
'being' acts as a link.
(Other definitions for wonder that I've seen before include "Phenomenon - marvel at it" , "Feeling of surprise and admiration" , "Marvellous person; feel doubt" , "Ponder" , "Scene of Alice's adventures" .)
