Takes in commercial and chooses (6)
I believe the answer is:
adopts
'takes in' is the definition.
('adopt' can be a synonym of 'take in')
'commercial and chooses' is the wordplay.
'commercial' becomes 'ad' (abbreviation for advertisement).
'and' means one lot of letters go next to another.
'chooses' becomes 'opts' (I've seen this before).
'ad'+'opts'='ADOPTS'
(Other definitions for adopts that I've seen before include "Takes into one's family legally" , "Takes as one's own, say child" , "Legally takes on (child)" , "Approves or accepts, a motion or accounts" , "Takes a child into one's family" .)
