Resident’s strange account about parking (8)
I believe the answer is:
occupant
'resident's' is the definition.
(synonyms)
'strange account about parking' is the wordplay.
'strange' is an anagram indicator.
'about' indicates putting letters inside.
'parking' becomes 'p' (abbreviation on road signs).
'account' anagrammed gives 'occuant'.
'occuant' enclosing 'p' is 'OCCUPANT'.
(Other definitions for occupant that I've seen before include "Inhabitant, resident" , "Insider" , "Homeowner or tenant" , "Inmate" , "Tenant - resident" .)
