Is it normal to not have a middle name?
Yep.Totally normal
Yes, it’s completely normal not to have a middle name. Plenty of people don’t, whether because of family or cultural traditions or simply their parents’ choice.
There’s no rule that you need a middle name. Some families use them, some don’t, and naming traditions vary widely across cultures and countries.
If a form asks for one, you can usually leave it blank or follow the form’s instructions. It’s just a name choice—not a missing piece of your identity.
