Provide a doctor with sick taking a turn (6)
I believe the answer is:
afford
'provide' is the definition.
(affording is a kind of providing)
'a doctor with sick taking a turn' is the wordplay.
'a doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor').
'with sick' becomes 'off' (I can't justify this - if you can you should believe this answer much more).
'taking' means one lot of letters go next to another.
'turn' is a reversal indicator.
'dr'+'off'+'a'='droffa'
'droffa' reversed gives 'AFFORD'.
Can you help me to learn more?
(Other definitions for afford that I've seen before include "Run to" , "Provide; be able to pay for" , "Give, provide" , "Provide; manage to pay for" , "Able to bear the cost of" .)
