Trifling group, united in support of Democrat (9)
I believe the answer is:
dalliance
'trifling' is the definition.
(I've seen this before)
'group united in support of democrat' is the wordplay.
I cannot really see how this works, but
'group' could be 'alliance' (alliance is a kind of group) and 'alliance' is present in the answer.
'democrat' could be 'd' and 'd' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dalliance that I've seen before include "time-wasting action" , "A casual romance" , "waste of time" , "Toying - trifling - delay" , "Flirting" .)
