Fleet I'll float round (8)
I believe the answer is:
flotilla
'fleet' is the definition.
(I know that flotilla is a type of fleet)
'i'll float round' is the wordplay.
'round' is an anagram indicator.
'ill'+'float'='illfloat'
'illfloat' with letters rearranged gives 'FLOTILLA'.
(Other definitions for flotilla that I've seen before include "many boats" , "A lot of craft" , "Fleet of small craft" , "Fleet of small warships" , "Fleet of small ships" .)
