* Noun: If it refers to a specific geographic area, like a neighborhood, then it's a noun.
* Example: "We're going to the Southside for dinner."
* Adjective: If it's describing something as being located in the south, it's an adjective.
* Example: "The Southside stadium is filled with fans."
* Adverb: While less common, it can be used as an adverb to indicate direction or location.
* Example: "Turn southside at the next corner."
So, it's important to look at the context to determine the correct part of speech.
