Planet seen in the art here (5)
I believe the answer is:
earth
'planet' is the definition.
(Earth is an example)
'in the art here' is the wordplay.
'in' indicates a hidden word.
'EARTH' is hidden in the letters of 'the art here'.
'seen' acts as a link.
(Other definitions for earth that I've seen before include "Dirty hole" , "Badger or fox burrow" , "Land" , "dirt" , "Where some creatures live" .)
