Many people search for “oases or oasis” because the two words look very similar. The difference is small, but the meaning changes depending on how many places you are talking about.
An oasis is a green place in the middle of a desert where water is found. In deserts, water is rare. Because of this, an oasis is very important for people, animals, and plants. Trees and grass often grow around an oasis because water is available there.
The word oases is simply the plural form of oasis. This means it is used when talking about more than one oasis.
The spelling change can confuse many writers because the word does not follow the normal English rule of adding “s” or “es.” Instead, the ending changes from -is to -es.
