How to spill rum with a murmur (5)
I believe the answer is:
twice
'how' is the definition.
Both the definition and answer are adverbs. Perhaps they are linked in a way I don't understand?
'spill rum with a murmur' is the wordplay.
I cannot quite understand how this works, but
'with' could be 'w' (abbreviation) and 'w' is found within the answer.
The remaining letters 'tice' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for twice that I've seen before include "Two times" , "Doubly" , "You only live -- (film)" , "Double in quantity" .)
