noun
oasis
oh-AY-sis/əʊˈeɪsɪs/
A place in a desert where water supports plant life.
Date palms and lush grasses surround the pool in this desert oasis.

Etymology
Greek oasis named a watered, fertile place in the desert. It probably reflects an Egyptian word meaning “dwelling place,” connecting the name with habitation.
In context
This oasis is fed by a hot volcanic spring. Slightly away from the stream of near boiling water, it's cooler and fish can live.
