Come in from barren terrain (5)

I believe the answer is:
enter
'come in' is the definition.
(synonyms)
'from barren terrain' is the wordplay.
'from' indicates a hidden word.
'ENTER' is hidden within 'barren terrain'.
(Other definitions for enter that I've seen before include "Infiltrate" , "Gain admission" , "Come/go in" , "Record (in a log)" , "Pierce" .)
