I'm assuming you're asking the wuchi hager naming system (NOT conversion from habesha) No. Middle name is just your second name. You always have a pair of names beka. First name and Middle name. This is for you. Last name is your family name. Your parents, your father's family, your siblings and your future wife will have the same last name. For example, John Kendrick Smith can be called John Smith and it'll be normal. Kendrick is just a useless middle name. If he wants, when John grows up, he can tell his friends to call him Kenny or Johnny-K as his nickname. Converting habesha names to this system is very weird because Ethiopians don't have last names or middle names. We only have a first name that's common with the foreign system.
