Seasoning sailor from Gibraltar? (4,4)
I believe the answer is:
rock salt
'seasoning sailor from gibraltar?' is the definition.
'rock salt' can be an answer for 'seasoning' (I've seen this before). I am not certain of the 'sailor from gibraltar?' bit.
'seasoning sailor' is the wordplay.
'seasoning' becomes 'rock' (I can't explain this - if you can you should give a lot more credence to this answer).
'sailor' becomes 'salt' (salt is a kind of sailor).
'rock'+'salt'='ROCK-SALT'
Can you help me to learn more?
(Other definitions for rock salt that I've seen before include "condiment" , "Mineral sodium chloride" , "mineral deposit" , "Seasoning" , "Mineral NaC One" .)
