A start in Greek? (5)
I believe the answer is:
alpha
I believe this is a triple definition!
'a' is the first definition.
(the Greek letter A)
'start' is the second definition.
(alpha is a kind of start)
'in' is a link.
'greek?' is the third definition.
(I have seen 'A Greek' mean 'alpha' so perhaps 'greek' could also mean 'alpha')
(Other definitions for alpha that I've seen before include "Early testing stage for new software or hardware" , "Beginning" , "- - and Omega" , "best score" , "star outshining the others" .)
