Light seen in Kent orchard (5)
I believe the answer is:
torch
'light' is the definition.
(torch is a kind of light)
'in kent orchard' is the wordplay.
'in' indicates a hidden word.
'TORCH' can be found hidden inside 'kent orchard'.
'seen' acts as a link.
(Other definitions for torch that I've seen before include "Deliberately set fire to" , "Set fire to; electric lamp" , "Burn maliciously" , "Source of light" , "A large candle" .)
