Get on? Get on after accommodating soldiers (5)
I believe the answer is:
agree
'get on? get on after accommodating soldiers' is the definition.
I can't tell whether this defines the answer.
'get on? get on' is the wordplay.
'get on?' becomes 'age' (synonyms).
'get' indicates putting letters inside.
'on' becomes 're' ('on' can be mean 'with reference to').
'age' placed around 're' is 'AGREE'.
Can you help me to learn more?
(Other definitions for agree that I've seen before include "Concur, acquiesce" , "Arrive at a settlement" , "Go well together" , "Concur - correspond" , "Hold the same view" .)
