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

I'm afraid I can't explain this answer.

(Other definitions for oasis that I've seen before include "Place of refreshment" , "Desert refuge" , "water you'll want here" , "Fertile place in a desert, watering-hole" , "Fertile area in 7?" .)

I've seen this clue in the Evening Standard.
