Each sufferer originally put on drugs gets better (5)
I believe the answer is:
eases
'gets better' is the definition.
The answer and definition can be both related to bodily activities as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
'each sufferer originally put on drugs' is the wordplay.
'each' becomes 'ea' (abbreviation).
'originally' indicates taking the first letters.
'put on' says to put letters next to each other (some letters go on or after others).
'drugs' becomes 'es' (ecstasy tablets).
The first letter of 'sufferer' is 's'.
'ea'+'s'+'es'='EASES'
Can you help me to learn more?
(Other definitions for eases that I've seen before include "Borders, margins" , "Makes less severe" , "Moves carefully" , "Softens" , "Moderates" .)
