The usual routine; back having a drink and something to eat (6)
I believe the answer is:
turnip
'something to eat' is the definition.
(turnip is a kind of food)
'the usual routine back having a drink' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'drink' could be 'nip' (I've seen this before) and 'nip' is found in the answer.
The remaining letters 'ur' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for turnip that I've seen before include "Fleshy edible white or yellow root" , "Root vegetable of the mustard family" , "what you eat?" , "veggie" , "Globular food plant" .)
