As a linguistic expert with a deep understanding of the nuances of the English language, I am well-equipped to address the intricacies of its grammar and usage. The word "campus" is derived from the Latin word "campus," which means "field." In the context of educational institutions, a "campus" refers to the land on which a university or college and its buildings are situated.

When discussing the plural form of "campus," it is important to consider both the historical and contemporary usage of the term. The traditional Latin plural form "campi" is occasionally used, especially in academic or formal contexts, particularly when referring to the grounds of colleges or universities. However, this form is not universally accepted and can sometimes be seen as archaic or overly formal.

On the other hand, the more common and universally accepted plural form is "campuses." This form is widely used in both spoken and written English and is understood by native speakers without confusion. The use of "campuses" adheres to the general rule in English that the plural of nouns ending in 'us' is typically formed by adding 'es'.

In summary, while "campi" may be seen in certain contexts, especially those with a Latinate influence, "campuses" is the more common and broadly accepted plural form of "campus." It is advisable to use "campuses" in most situations to ensure clarity and avoid any potential misunderstanding.
