* Noun: When it refers to a specific place, like "We visited the town of Springfield."
* Adjective: When it describes something related to a town, like "The town square was bustling."
* Verb: When it means to form a town, like "They towned together to create a new community." (This usage is uncommon and more likely to be found in older or regional dialects.)
So, without context, we can't definitively say what part of speech "town" is.
