In Arab culture, we don't have middle names. Instead, we have نَسَب, which literally means "lineage". (Linguistically, the word نَسَب comes from نِسبَة, which literally means "relation".) This refers to the practice of using family lineage in names, specifically the paternal family lineage. We put our father's name, followed by our grandfather's name, followed by our great-grandfather's name, etc. Some people can trace their nasab back many generations.

So our names look something like this: [first name] [father's name] [grandfather's name] [great-grandfather's name] [great-great-grandfather's name] [family name]

In some countries, the word بن (son of)  or بنت (daughter of) is used between the names:

Man's name: [first name] بن [father's name] بن [grandfather's name] بن [great-grandfather's name] بن [great-great-grandfather's name] [family name]

Woman's name: [first name] بنت [father's name] بن [grandfather's name] بن [great-grandfather's name] بن [great-great-grandfather's name] [family name]

We also have something called كُنيَة (literally, "nickname"), and it's a nickname derived from the eldest son's name. For example, if your name is Muhammad and you're the eldest son, your father is called أبو محمد (father of Muhammad) and your mother is called أم محمد (mother of Muhammad).

The kunya is not used in official documents, but it's used a lot in everyday life.
