Binding of things dedicated about returned soldier (10)
I believe the answer is:
obligatory
'binding of things' is the definition.
'obligatory' can be an answer for 'binding' (I've seen this before). I am not sure about the 'of things' bit.
'dedicated about returned soldier' is the wordplay.
'dedicated' becomes 'oblatory' (I can't explain this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'returned' is a reversal indicator.
'soldier' becomes 'GI' (GI can mean a US soldier).
'gi' reversed gives 'ig'.
'oblatory' going around 'ig' is 'OBLIGATORY'.
Can you help me to learn more?
(Another definition for obligatory that I've seen is " Binding".)
