Talked for a day with German agreement (5)

I believe the answer is:

jawed

'talked' is the definition.
(jawing is a kind of talking)

'a day with german agreement' is the wordplay.
'a day' becomes 'wed'.
'with' means one lot of letters go next to another.
'german agreement' becomes 'ja' (I've seen this in other clues).
'wed' put after 'ja' is 'JAWED'.

'for' is the link.

(Another definition for jawed that I've seen is " did converse".)

I've seen this clue in The Independent.
