Choker left in unusual cargo area (12)
I believe the answer is:
stranglehold
'choker' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'left in unusual cargo area' is the wordplay.
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'unusual' becomes 'strange' (similar in meaning).
'cargo area' becomes 'hold' (synonyms).
'l' going into 'strange' is 'strangle'.
'strangle'+'hold'='STRANGLEHOLD'
Can you help me to learn more?
(Other definitions for stranglehold that I've seen before include "tight grip!" , "exclusive control?" , "Complete control" , "Inexorable grip" , "total control" .)
