One turns up incline in advanced driving area (8)
I believe the answer is:
attendee
'one turns up' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'incline in advanced driving area' is the wordplay.
'incline' becomes 'tend' (synonyms).
'in' indicates putting letters inside.
'advanced' becomes 'a'.
'driving area' becomes 'tee' (a golfer drives a golf ball from a tee).
'a'+'tee'='atee'
'tend' inserted inside 'atee' is 'ATTENDEE'.
Can you help me to learn more?
(Other definitions for attendee that I've seen before include "Conference participant" , "One at a meeting; teen date (anag.)" , "One going to, eg, conference" , "Someone who is here" , "One shows up" .)
