Planet near the centre (5)
I believe the answer is:
earth
'planet' is the definition.
(Earth is an example)
'near the centre' is the wordplay.
'centre' says the answer is hidden in the clue (hidden in the middle of the letters).
'EARTH' is hidden within 'near the'.
(Other definitions for earth that I've seen before include "Connection between an electrical device and conductor" , "hideaway" , "brownish pigment?" , "Soil; electrical connection" , "Land" .)
