Yes, in Germany government is good according to journalist, but rough-edged (6)
I believe the answer is:
jagged
'rough-edged' is the definition.
(I've seen this before)
'yes in germany government is good according to' is the wordplay.
'yes in germany' becomes 'ja' ('yes' in German).
'government' becomes 'g' (abbreviation for government).
'is good' becomes 'g' (abbreviation).
'according to' becomes 'ed' (I can't explain this - if you can you should believe this answer much more).
'ja'+'g'+'g'+'ed'='JAGGED'
'journalist but' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for jagged that I've seen before include "Having an irregularly notched or toothed edge" , "With a sharp and uneven edge" , "With a sharply uneven edge" , "Notched; rough-edged; uneven" , "Having outline with sharp projections" .)
