Stick a sovereign among some of the guests! (4)
I believe the answer is:
glue
'stick' is the definition.
(to stick with glue)
'a sovereign among some of the guests' is the wordplay.
I cannot quite understand how this works, but
'sovereign' could be 'l' (sovereign can mean pound and therefore L) and 'l' is found within the answer.
The remaining letters 'gue' 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).
Can you help me to learn more?
(Other definitions for glue that I've seen before include "Sticky substance" , "Paste" , "agent with sticking power" , "Stick together" , "Fixative" .)
