In Urdu oddly, map showing hilly area (6)
I believe the answer is:
upland
'hilly area' is the definition.
(I've seen this before)
'in urdu oddly map' is the wordplay.
'in' indicates putting letters inside.
'oddly' indicates alternate letters.
'map' becomes 'plan' (I've seen this before).
The alternating letters of 'urdu' are 'ud'.
'ud' going around 'plan' is 'UPLAND'.
'showing' acts as a link.
(Other definitions for upland that I've seen before include "High or hilly terrain" , "Area of high ground" , "Hilly country" , "Area of hills" , "Elevated area" .)
