Emphatic type dismissed, caught (4)
I believe the answer is:
bold
'emphatic type' is the definition.
(bold type adds emphasis)
'dismissed caught' is the wordplay.
'dismissed' becomes 'bowled' (dismissed in cricket).
'caught' indicates a 'sounds like' (homophone) clue (heard).
'bowled' is a homophone of 'BOLD'.
(Other definitions for bold that I've seen before include "like Ben Battle" , "Daring, maybe impudent" , "Confident, daring" , "Intrepid" , "Confidently courageous" .)
