Send flower to support tense husband (6)
I believe the answer is:
thrill
'send' is the definition.
(I've seen this in another clue)
'flower to support tense husband' is the wordplay.
'flower' becomes 'rill' (I can't justify this - if you can you should believe this answer much more).
'to support' is a charade indicator (letters next to each other) (in a down clue, some letters hold up others).
'tense' becomes 't' (abbreviation used in many dictionaries).
'husband' becomes 'h' (abbreviation).
't'+'h'='th'
'rill' put after 'th' is 'THRILL'.
Can you help me to learn more?
(Other definitions for thrill that I've seen before include "Sudden rush of pleasure" , "D. W. _, pioneer US film director; rigs fifth (anag.)" , "bring a tingle of excitement" , "Excited sensation" , "Sudden sensation of excitement" .)
