What to take when unwell in the outskirts of Paris (5)
I believe the answer is:
pills
'what to take' is the definition.
I can't tell whether this definition defines the answer.
'unwell in the outskirts of paris' is the wordplay.
'unwell' becomes 'i'll' (similar in meaning).
'in the' means one lot of letters goes inside another.
'outskirts of paris' becomes 'PS' (first and last letters of 'Paris').
'ill' placed within 'ps' is 'PILLS'.
'when' is the link.
Can you help me to learn more?
(Other definitions for pills that I've seen before include "Medicine to be swallowed" , "Tablets of medicine" , "Medication" .)
