US narcs regularly lost supplies of drugs (5)
I believe the answer is:
deals
'supplies of drugs' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'us narcs regularly lost' is the wordplay.
'us narcs' becomes 'dea' (I am not sure about this - if you are sure you should believe this answer much more).
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
The alternating letters of 'lost' are 'ls'.
'dea'+'ls'='DEALS'
Can you help me to learn more?
(Other definitions for deals that I've seen before include "Passes cards around" , "Bargains" , "Trades" , "Hands around the cards" , "Business agreements" .)
