A weekend with a girl, afloat (5)
I believe the answer is:
kayak
'a weekend' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'with a girl afloat' is the wordplay.
'with' is a charade indicator (letters next to each other).
'a girl' becomes 'Kay'.
'afloat' becomes 'ak' (I can't justify this - if you can you should believe this answer much more).
'kay' put next to 'ak' is 'KAYAK'.
Can you help me to learn more?
(Other definitions for kayak that I've seen before include "A small covered canoe" , "Inuit craft" , "Small canoe used by Eskimo" , "Inuit canoe" , "Type of canoe" .)
