Smiled broadly (6)
I believe the answer is:
beamed
'smiled broadly' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for beamed that I've seen before include "Smiled broadly like sun ray" , "Shone brightly or smiled widely" , "Smiled widely - having support" , "Smiled broadly - positively shone" , "Smiled broadly and warmly" .)
