With broken rib, young man turned up for wedding (6)
I believe the answer is:
bridal
'wedding' is the definition.
(bridal is a kind of wedding)
'with broken rib young man turned up' is the wordplay.
'with' says to put letters next to each other.
'broken' indicates anagramming the letters.
'young man' becomes 'lad' (I've seen this before).
'turned up' says the letters should be written in reverse.
'lad' in reverse letter order is 'dal'.
'rib' with letters rearranged gives 'bri'.
'bri'+'dal' is 'BRIDAL'.
'for' acts as a link.
(Other definitions for bridal that I've seen before include "To do with wedding - perhaps a suite" , "Hotel suite for newly-weds" , "Nuptial" , "of the train puller?" , "Newly-wed" .)
