Natural surroundings, some with a bit attached (7)
I believe the answer is:
habitat
'natural surroundings' is the definition.
(I've seen this before)
'some with a bit attached' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'HABITAT' is hidden in the letters of 'with a bit attached'.
(Other definitions for habitat that I've seen before include "place haunted" , "Natural home and surroundings" , "Environment in which an organism normally lives" , "Natural home of a plant or animal" , "Surrender" .)
