Look at some conventional and new starters (4)
I believe the answer is:
scan
'look at' is the definition.
(to scan something is to look at it briefly)
'some conventional and new starters' is the wordplay.
'starters' suggests taking the first letters.
The initial letters of 'some conventional and new' is 'SCAN'.
(Other definitions for scan that I've seen before include "make a detailed copy of" , "Medical examination" , "Survey; screen" , "Cast an eye over" , "Examine, view" .)
