Extent of suspicion about Germany (7)
I believe the answer is:
breadth
'extent' is the definition.
(thesaurus)
'suspicion about germany' is the wordplay.
'suspicion' becomes 'breath' (I've seen this in other clues).
'about' means one lot of letters goes inside another.
'germany' becomes 'd' (international vehicle registration code).
'breath' going around 'd' is 'BREADTH'.
'of' acts as a link.
(Other definitions for breadth that I've seen before include "Liberality" , "Liberal view" , "Lateral extent" , "Width, thickness" , "Latitude, broadness" .)
