Goodbye to a Frenchman (5)

I believe the answer is:

adieu

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

'goodbye' is the definition.
(synonyms)

'a frenchman' is the wordplay.
'frenchman' becomes 'dieu' (I am not sure about this - if you are sure you should believe this answer much more).
'a'+'dieu'='ADIEU'

'to' is the link.

Can you help me to learn more?

(Other definitions for adieu that I've seen before include "Goodbye, mon ami!" , "the last word in France" , "Adios, Arrivederci" , "Fare thee well!" , "Goodbye in France" .)

I've seen this clue in The Globe and Mail.
