Warble about husband giving feeling of excitement (6)
I believe the answer is:
thrill
'feeling of excitement' is the definition.
(I've seen this before)
'warble about husband' is the wordplay.
'warble' becomes 'trill' ('trill' can be a synonym of 'warble').
'about' means one lot of letters goes inside another.
'husband' becomes 'h'.
'trill' going around 'h' is 'THRILL'.
'giving' is the link.
(Other definitions for thrill that I've seen before include "Shudder of excitement" , "Buzz" , "Excited feeling" , "Intense feeling of delight or excitement" , "Exhilarate, excite" .)
