State of unforeseen evadable proportions (6)
I believe the answer is:
nevada
'state' is the definition.
(Nevada is an example)
'of unforeseen evadable proportions' is the wordplay.
'of' indicates the answer is hidden within the clue.
'NEVADA' is hidden in the letters of 'unforeseen evadable proportions'.
(Other definitions for nevada that I've seen before include "American state, capital Carson City" , "Western US state" , "State of western USA" , "US state, NV" , "The Silver State" .)
