Night drinking, primarily getting stuck into lager? (6)
I believe the answer is:
bender
'night drinking primarily getting stuck into lager?' is the definition.
I can't judge whether this definition defines the answer.
'night drinking primarily getting stuck into lager?' is the wordplay.
'primarily' says to take the initial letters.
'getting stuck into' means one lot of letters goes inside another.
'lager?' becomes 'beer' (lager is a kind of beer).
The first letters of 'night drinking' is 'nd'.
'nd' placed into 'beer' is 'BENDER'.
(Other definitions for bender that I've seen before include "Booze-up" , "Non-stop drinking" , "A wild drinking session, sounds twisted" , "Bout of heavy drinking" , "What might leave one legless" .)
