With no parking, stay in charge of patient (5)
I believe the answer is:
stoic
'patient' is the definition.
(I've seen this before)
'with no parking stay in charge' is the wordplay.
'with no' suggests deleting specific letters.
'parking' becomes 'p'.
'stay' becomes 'stop' (stop is a kind of stay).
'in charge' becomes 'ic'.
'stop' with 'p' taken away is 'sto'.
'sto'+'ic'='STOIC'
'of' acts as a link.
(Other definitions for stoic that I've seen before include "Greek in school" , "Zeno, say" , "Uncomplaining; philosopher" , "he's not complaining" , "philosophical type" .)
