One double parking in New York needs to be quick (5)
I believe the answer is:
nippy
'to be quick' is the definition.
(I've seen this before)
'one double parking in new york' is the wordplay.
'one' becomes 'i' (Roman numeral).
'double' says to double the letters.
'parking' becomes 'p'.
'in' is an insertion indicator.
'new york' becomes 'ny'.
'p' doubled is 'pp'.
'i'+'pp'='ipp'
'ipp' put inside 'ny' is 'NIPPY'.
'needs' acts as a link.
(Other definitions for nippy that I've seen before include "brisk" , "Frosty - quick" , "active" , "Fast - cold" , "inclined to bite?" .)
