steppe

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

'it's plain' is the definition.
(steppe is a kind of plain)

I don't understand the rest of the clue.

(Other definitions for steppe that I've seen before include "crosses Siberia" , "Large area of flat grassland in Europe or Siberia" , "plain territory" , "Flat area of eastern Europe or Russia" , "(Russian) grassy plain" .)

I've seen this clue in The Globe and Mail.
