Proceed to a port in India (3)
I believe the answer is:
goa
'in india' is the definition.
(I've seen this before)
'proceed to a port' is the wordplay.
I cannot quite understand how this works, but
'proceed' could be 'go' (synonyms) and 'go' is found in the answer.
'a' is within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for goa that I've seen before include "Indian island state" , "Indian port" , "West coast Indian state" , "stately annexation of India" , "Indian resort" .)
