Soldier on the go? (6)
I believe the answer is:
sentry
'soldier on the go?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'soldier on the go?' is the wordplay.
'soldier' becomes 'sen' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' means one lot of letters go next to another.
'the go?' becomes 'try' (both can mean an attempt).
'sen'+'try'='SENTRY'
Can you help me to learn more?
(Other definitions for sentry that I've seen before include "Guard on watch" , "Picket" , "Lookout person" , "Military lookout" , "One keeps watch" .)
