Last to work with doctor? Not quite (6)
I believe the answer is:
almost
'not quite' is the definition.
(I've seen this before)
'last to work with doctor?' is the wordplay.
'to work' is an anagram indicator (letters worked into a new order).
'with' means one lot of letters goes inside another.
'doctor?' becomes 'mo' (medical officer).
'last' with letters rearranged gives 'alst'.
'alst' going around 'mo' is 'ALMOST'.
(Other definitions for almost that I've seen before include "practically" , "Virtually" , "Not entirely" , "Not totally" , "As good as" .)
