illa

Illa is a term that can refer to several different things, depending on language and context. It is commonly encountered as a word in classical Latin, and it also appears as a proper name in various cultures or as part of place names. Because of this variety, a disambiguation is often needed.

In Classical Latin, illa is the feminine demonstrative pronoun and adjective meaning "that" or "that one," used to refer to a feminine noun or to emphasize a previously mentioned subject. The corresponding masculine form is ille and the neuter form illud, with related plural forms used for "those" or "that ones" depending on gender and case.

In modern usage, Illa can function as a surname or given name in some communities, and it appears in the names of places or geographic features in various languages. Without additional context, it can be difficult to determine which sense of illa is intended.
