ignore

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

'pass over' is the definition.
(thesaurus)

'a ravaged region' is the wordplay.
'region' can be anagrammed to 'IGNORE'.
However, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for ignore that I've seen before include "Turn a blind eye to" , "Send to Coventry" , "Blank" , "Region (anag)" , "Disregard - cut" .)

I've seen this clue in the Evening Standard.
