Gobi or Taklamakan (6)
I believe the answer is:
desert
'gobi or taklamakan' is the definition.
(I know that Gobi Desert is a Desert)
This is the entire clue.
(Other definitions for desert that I've seen before include "Sandy waste" , "Defect, forsake" , "Uncultivated" , "Abandon; dull area" , "Abscond from forces" .)
