Range well stripped, in part (9)
I believe the answer is:
selection
'range' is the definition.
(selection can mean a range or variety of things)
'well stripped in part' is the wordplay.
'stripped' says to take the centre (outside letters removed).
'in' is an insertion indicator.
'part' becomes 'section' (synonyms).
The centre of 'well' is 'el'.
'el' inserted inside 'section' is 'SELECTION'.
(Other definitions for selection that I've seen before include "Horse tipped for betting" , "Act of choosing" , "Choice, pick" .)
