Parking by worthless hole (6)
I believe the answer is:
plight
'hole' is the definition.
(thesaurus)
'parking by worthless' is the wordplay.
'parking' becomes 'p'.
'by' is a charade indicator (letters next to each other).
'worthless' becomes 'light' ('light' can be similar in meaning to 'worthless').
'p'+'light'='PLIGHT'
(Other definitions for plight that I've seen before include "Dangerous or difficult situation" , "Predicament, difficulty" , "Promise - trouble" , "Jam" , "Quandary, predicament" .)
