Choose from selection (5)
I believe the answer is:
elect
'choose' is the definition.
(I know that elect is a kind of choose)
'from selection' is the wordplay.
'from' indicates the answer is hidden within the clue.
'ELECT' can be found hidden inside '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" .)
