Get rid of toboggan after the flood? (6)
I believe the answer is:
deluge
'the flood?' is the definition.
('deluge' can be a synonym of 'flood')
'get rid of toboggan after' is the wordplay.
'get rid of' becomes 'de' (I can't justify this - if you can you should believe this answer much more).
'toboggan' becomes 'luge' (synonyms).
'after' says to put letters next to each other.
'de'+'luge'='DELUGE'
Can you help me to learn more?
(Other definitions for deluge that I've seen before include "A heavy fall of rain (6)" , "Severe flood" , "Inundation" , "Great flood" , "Torrential rain" .)
