One receptacle in the street is hardly enough (5)
I believe the answer is:
scant
'hardly enough' is the definition.
(I've seen this in another clue)
'one receptacle in the street' is the wordplay.
'one receptacle' becomes 'can' (type of receptacle or vessel).
'in the' is an insertion indicator.
'street' becomes 'st' (abbreviation).
'can' going into 'st' is 'SCANT'.
'is' acts as a link.
(Other definitions for scant that I've seen before include "Deficient, sparing" , "Barely adequate" , "Bare" , "Barely sufficient" , "Little" .)
