He travels overseas to get home (8)
I believe the answer is:
emigrant
'he travels overseas to get home' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he' is the wordplay.
I cannot quite understand how this works, but
'he' could be 'grant' and 'grant' is found within the answer.
The remaining letters 'emi' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for emigrant that I've seen before include "One going abroad permanently" , "one on the way out?" , "One leaving for another country" , "Write carelessly" , "Time Gran went abroad to settle" .)
