Ill during fast? Go here for medicine (8)
I believe the answer is:
pharmacy
'here for medicine' is the definition.
'pharmacy' can be an answer for 'medicine' (pharmacy is a kind of medicine). I'm not certain of the 'here for' bit.
'ill during fast?' is the wordplay.
'ill' becomes 'harm' (as in doing people ill).
'during' is an insertion indicator.
'fast?' becomes 'pacy' (I've seen this in other clues).
'harm' put into 'pacy' is 'PHARMACY'.
'go' acts as a link.
Can you help me to learn more?
(Other definitions for pharmacy that I've seen before include "Where drugs are dispensed" , "A chemist's shop where prescriptions are dispensed" , "Business" , "Science of dispensing drugs" , "Place where drugs are prepared or sold" .)
