Be on a list queuing outside clubs (7)
I believe the answer is:
incline
'be on a list' is the definition.
'incline' can be an answer for 'list' (list can mean to lean or roll). I'm unsure of the 'be on a' bit.
'queuing outside clubs' is the wordplay.
'queuing' becomes 'in line' (standing in line).
'outside' means one lot of letters goes inside another (some letters go outside others).
'clubs' becomes 'c' (abbreviation in card games).
'inline' enclosing 'c' is 'INCLINE'.
Can you help me to learn more?
(Other definitions for incline that I've seen before include "Turn" , "Have a tendency to do or be something" , "Be disposed to" , "tip" , "Lean, slope" .)
