... staying in one, maybe old men get sozzled (9)
I believe the answer is:
lodgement
'staying in one maybe' is the definition.
I can't judge whether this defines the answer.
'old men get sozzled' is the wordplay.
'sozzled' indicates anagramming the letters.
'old'+'men'+'get'='oldmenget'
'oldmenget' is an anagram of 'LODGEMENT'.
Can you help me to learn more?
(Other definitions for lodgement that I've seen before include "position in enemy territory" , "Placing" , "Occupied position" , "accommodation" , "cash deposit" .)
