One clear about parking being awkward (5)
I believe the answer is:
inept
'awkward' is the definition.
('inept' can be a synonym of 'awkward')
'one clear about parking' is the wordplay.
'one' becomes 'i' (Roman numeral).
'clear' becomes 'net' (as in net profit).
'about' means one lot of letters goes inside another.
'parking' becomes 'p'.
'net' going around 'p' is 'nept'.
'i'+'nept'='INEPT'
'being' is the link.
(Other definitions for inept that I've seen before include "Silly or senseless" , "Hopeless; bungling" , "Futile" , "Awkward, showing no skill" , "Ham-fisted" .)
