Some boas established in lush places (5)
I believe the answer is:
oases
'lush places' is the definition.
The answer and definition can be both locations as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'some boas established in' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'OASES' is hidden within 'boas established in'.
Can you help me to learn more?
(Other definitions for oases that I've seen before include "Green desert spots" , "Fertile desert spots" , "These sanctuaries" , "Fertile tracts in a desert" , "Fertile areas in deserts" .)
