Greek starter in local pharmacy (5)
I believe the answer is:
alpha
'greek starter' is the definition.
'alpha' can be an answer for 'starter' (I've seen this before). I'm unsure of the 'greek' bit.
'in local pharmacy' is the wordplay.
'in' says the answer is hidden in the clue.
'ALPHA' is hidden in the letters of 'local pharmacy'.
Can you help me to learn more?
(Other definitions for alpha that I've seen before include "First, best quality" , "starter" , "Dominant" , "Early testing stage for new software or hardware" , "First in order of importance (for a Greek?)" .)
