Improper presents of food and some cigs (5)
I believe the answer is:
bungs
'improper presents' is the definition.
The answer and definition can be both to do with ownership as well as being verbs in their -s form.
Maybe you can see a link between them that I don't see?
'food and some cigs' is the wordplay.
'food' becomes 'bun' (bun is a kind of food).
'and' means one lot of letters go next to another.
'some cigs' becomes 'gs' (I can't justify this - if you can you should give a lot more credence to this answer).
'bun'+'gs'='BUNGS'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for bungs that I've seen before include "bribes?" , "Puts a stop to" .)
