Salty as the stormy sea around some liners (6)
I believe the answer is:
saline
'salty' is the definition.
(synonyms)
'the stormy sea around some liners' is the wordplay.
'the stormy' indicates anagramming the letters.
'around' is an insertion indicator.
'some liners' becomes 'lin' (I can't justify this - if you can you should believe this answer much more).
'sea' is an anagram of 'sae'.
'sae' placed around 'lin' is 'SALINE'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for saline that I've seen before include "Intravenous feeding" , "solution" , "Salty to aliens" , "Like contents of cellar" , "Containing or tasting of salt" .)
