Resident giving muddled account about parking (8)
I believe the answer is:
occupant
'resident' is the definition.
('occupant' can be a synonym of 'resident')
'muddled account about parking' is the wordplay.
'muddled' indicates anagramming the letters.
'about' indicates putting letters inside.
'parking' becomes 'p'.
'account' anagrammed gives 'occuant'.
'occuant' enclosing 'p' is 'OCCUPANT'.
'giving' is the link.
(Other definitions for occupant that I've seen before include "Insider" , "Indweller" , "Inmate" , "Holder of a position or office" , "One in residence" .)
