La mer, most disturbed here? (9)
I believe the answer is:
maelstrom
'here?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'la mer most disturbed' is the wordplay.
'disturbed' indicates anagramming the letters.
'la'+'mer'+'most'='lamermost'
'lamermost' with letters rearranged gives 'MAELSTROM'.
(Other definitions for maelstrom that I've seen before include "great confusion" , "Whirlpool, turmoil" , "Strong circular current of water" , "violent upheaval" , "danger to shipping" .)
