Completed? In return, we nod (4)

Ross

I believe the answer is:

done

I'm a little stuck... Click here to teach me more about this clue!

'completed?' is the definition.
(something that's been completed has been done)

'return we nod' is the wordplay.
'return' is a reversal indicator.
'we' becomes 'e' (I can't justify this - if you can you should believe this answer much more).
'e'+'nod'='enod'
'enod' written backwards gives 'DONE'.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for done that I've seen before include "This settled" , "Achieved" , "Concluded (and dusted?)" , "Thoroughly cooked; accomplished" , "This sort of thing is socially acceptable" .)

I've seen this clue in the Sydney Morning Herald.
