Enterprising school principal in India? (2-5)
I believe the answer is:
go-ahead
'enterprising' is the definition.
(I've seen this before)
'school principal in india?' is the wordplay.
I cannot quite see how this works, but
'principal' could be 'head' (synonyms) and 'head' is found in the answer.
'in india?' could be 'goa' (I've seen this before) and 'goa' is located in the answer.
No letters remain.
This explanation may well be incorrect...
(Other definitions for go-ahead that I've seen before include "Enterprisingly progressive" , "Permission to proceed" , "Pioneering (green light?)" , "Up-and-coming - authorisation" , "Enterprising" .)
