Here's why it's likely not a fraternity:
* No established presence: There is no widely known or recognized organization called "Samahang Ilocano" that operates as a fraternity.
* Fraternities have specific structures: Fraternities have specific initiation rituals, membership requirements, and often a social or philanthropic focus, which is not clear from the term "Samahang Ilocano."
It's possible that:
* It's a local organization: There might be a local, informal group or organization in an Ilocano community that calls itself "Samahang Ilocano."
* It's a cultural group: The term might refer to a cultural association that promotes Ilocano heritage, language, or traditions.
