Offered to host wildly excessive dance (7)
I believe the answer is:
gavotte
'dance' is the definition.
(I know that gavotte is a type of social dancing)
'offered to host wildly excessive' is the wordplay.
I cannot quite see how this works, but
'excessive' could be 'ott' (short for 'over the top') and 'ott' is located in the answer.
The remaining letters 'gave' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for gavotte that I've seen before include "Old formal French dance" , "Veto tag on the old dance" , "Dance of French origin" , "steps taken" , "Former French dance" .)
