Common to find extra starting price studied (10)
I believe the answer is:
widespread
'common' is the definition.
(I've seen this before)
'extra starting price studied' is the wordplay.
'extra' becomes 'wide' (cricket term).
'starting price' becomes 'sp'.
'studied' becomes 'read' (I've seen this before).
'wide'+'sp'+'read'='WIDESPREAD'
'to find' acts as a link.
(Other definitions for widespread that I've seen before include "common" , "broad" , "Extensive" , "Generally prevalent" , "found in many places" .)
