* Plateau (singular) refers to a single, flat, elevated area of land.
* Plateaux (plural) refers to multiple flat, elevated areas of land.
Essentially, "plateau" is the singular form, while "plateaux" is the plural form.
Here's an example:
* "The Tibetan Plateau is the highest and largest plateau in the world." (singular)
* "We visited several plateaux during our trip to the Andes." (plural)
While "plateaus" is also used as a plural form, it's considered less formal and less common than "plateaux". However, both are grammatically correct.
