Nick is grabbing drink with yen to relax (4,2,4)
I believe the answer is:
take it easy
'relax' is the definition.
(I know that take it easy is a type of relax)
'nick is grabbing drink with yen' is the wordplay.
'nick' becomes 'take' (nick can informally mean to steal).
'grabbing' is an insertion indicator.
'drink with' becomes 'tea' (tea is a drink. I am not sure about the 'with' bit.).
'yen' becomes 'y' (resembles the symbol for the currency of Japan).
'is' placed around 'tea' is 'iteas'.
'take'+'iteas'+'y'='TAKE IT EASY'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for take it easy that I've seen before include "to rest" , "Relax" , "Lighten up" , "Avoid stress - remain calm" , "avoid exertion" .)
