Stash away in the cellar? (4)
I believe the answer is:
salt
'cellar?' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'stash away in the' is the wordplay.
'stash' becomes 'sl' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'away' becomes 'A' (abbreviation as used in sports fixtures).
'in' means one lot of letters goes inside another.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'sl' placed around 'a' is 'sal'.
'sal'+'t'='SALT'
Can you help me to learn more?
(Other definitions for salt that I've seen before include "Brackish" , "Condiment - experienced sailor" , "dry wit" , "Liveliness" , "Preserve" .)
