Extent of wind across Germany (7)

Ross

I believe the answer is:

breadth

'extent' is the definition.
(thesaurus)

'wind across germany' is the wordplay.
'wind' becomes 'breath' (breath is a kind of wind**).
'across' is an insertion indicator.
'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 "Extent from side to side" , "Wide measurement" , "Wideness" , "Lateral extent" , "Red bath (anag)" .)

I've seen this clue in The Telegraph.
