Divine creature felt naked beside knight clad in silver (5)
I believe the answer is:
angel
'divine creature' is the definition.
'felt naked beside knight clad in silver' is the wordplay.
'naked' indicates the central letters.
'beside' is a charade indicator (letters next to each other) (I've seen this in other clues).
'knight' becomes 'n' (chess).
'clad in' is an insertion indicator.
'silver' becomes 'ag' (Ag is the chemical symbol for silver).
The middle letters of 'felt' are 'el'.
'n' inserted into 'ag' is 'ang'.
'el' put after 'ang' is 'ANGEL'.
(Other definitions for angel that I've seen before include "darling!" , "Cloud resident?" , "local to Islington" , "Guardian spirit; theatre investor" , "One usually obliging" .)
