Treatment for the troubles that follow a poor start (5)
I believe the answer is:
pills
'treatment for the' is the definition.
I can't judge whether this defines the answer.
'troubles that follow a poor start' is the wordplay.
'troubles' becomes 'ills' ('ill' can be a synonym of 'trouble').
'that follow' is a charade indicator (letters next to each other).
'start' says to take the initial letters.
The initial letter of 'poor' is 'p'.
'ills' after 'p' is 'PILLS'.
Can you help me to learn more?
(Other definitions for pills that I've seen before include "Tablets of medicine" , "Medication" , "Medicine to be swallowed" .)
