Dashing husband pursues a risk, sadly (6)
I believe the answer is:
rakish
'dashing' is the definition.
(I know that dashing can be written as rakish)
'husband pursues a risk sadly' is the wordplay.
'husband' becomes 'h'.
'pursues' means one lot of letters go next to another.
'sadly' indicates an anagram.
'a'+'risk'='arisk'
'arisk' is an anagram of 'rakis'.
'h' after 'rakis' is 'RAKISH'.
(Other definitions for rakish that I've seen before include "Dapper" , "Jaunty and irresponsible" , "Jaunty; dissolute" , "Dashing and slightly disreputable" , "Jaunty; fast-looking (boat)" .)
