Intermediate to put down stake, then go north (7)
I believe the answer is:
'intermediate to' is the definition.
(I've seen this before)
'down stake then go north' is the wordplay.
'down stake' becomes 'bet' (synonyms. I am not sure about the 'down' bit.).
'then' means one lot of letters go next to another.
'go' becomes 'wee' (both can mean to urinate).
'north' becomes 'N' (abbreviation).
'put' acts as a link.
Can you help me to learn more?
(Other definitions for between that I've seen before include "Amongst" , "needle, not the smallest"" , "Don't tell anyone else..." , "In the intervening space" , "In the space dividing" .)
