Floater accepts Liberal waffle (7)
I believe the answer is:
blather
'waffle' is the definition.
(thesaurus)
'floater accepts liberal' is the wordplay.
I cannot really understand how this works, but
'liberal' could be 'l' (abbreviation) and 'l' is present in the answer.
The remaining letters 'bather' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for blather that I've seen before include "Rubbishy old talk, foolish chat" , "Foolish and irrelevant talk" , "Long-winded talk making little sense" , "Foolish chatter, just oul' talk" , "Palaver, prattle" .)
