What’s the Plural of Oasis?

The correct oasis plural form is oases.

• Singular: oasis

• analysis → analyses
• thesis → theses

Why Is the Oasis Plural Form “Oases”?

The word oasis comes from Greek óasis and Latin oasis. In Greek-derived English words, the ending -is usually becomes -es in the plural. That’s why the oasis plural form is spelled o-a-s-e-s.

Even though it looks different in writing, the pronunciation also changes:

• Oasis: oh-AY-sis
• Oases: oh-AY-seez
