A bit of a procession is buoyant (6)
I believe the answer is:
afloat
'buoyant' is the definition.
(I've seen this in another clue)
'a bit of a procession' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
'bit' could be 'o' (resembles 0, a binary digit or bit) and 'o' is located in the answer.
The remaining letters 'flat' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'is' acts as a link.
Can you help me to learn more?
(Other definitions for afloat that I've seen before include "Buoyant: solvent" , "With one's head above water" , "On board at sea, on ship" , "Still solvent" , "Aboard ship" .)
