Start to care about western team (4)
I believe the answer is:
crew
'team' is the definition.
(I know that crew is a type of team)
'start to care about western' is the wordplay.
'start to' indicates taking the first letters.
'about' becomes 're' ('re' means regarding or about).
'western' becomes 'w'.
The first letter of 'care' is 'c'.
'c'+'re'+'w'='CREW'
(Other definitions for crew that I've seen before include "Train team" , "eight, say" , "Ship/plane workers" , "Rowing team" , "Ship/plane operators" .)
