Purgative from sailors in Surrey? (5,5)
I believe the answer is:
epsom salts
'purgative from sailors in surrey?' is the definition.
'epsom salts' can be an answer for 'purgative' (I've seen this before). I am not sure about the 'from sailors in surrey?' bit.
'purgative from sailors' is the wordplay.
'purgative' becomes 'epsom' (I can't explain this - if you can you should give a lot more credence to this answer).
'from' is a charade indicator (letters next to each other).
'sailors' becomes 'salts' (salt is a kind of sailor).
'epsom'+'salts'='EPSOM SALTS'
Can you help me to learn more?
(Other definitions for epsom salts that I've seen before include "Medicine taken for heartburn and constipation" , "Purgative" , "They should clear out!" , "a purge" , "Medicinal preparation" .)
