Choose from selection (5)
I believe the answer is:
elect
'choose' is the definition.
(I know that elect is a more specific form of choose)
'from selection' is the wordplay.
'from' indicates a hidden word.
'ELECT' is hidden in the letters of 'selection'.
(Other definitions for elect that I've seen before include "Vote to put into power" , "Choose by vote" , "Opt for; chosen" , "Choose; singled out" , "Choose by ballot" .)
