Arabic names: ism, nasab, kunya, and how to address someone
A full Arabic name can be a long chain: a given name (ism), followed by "son of" or "daughter of" links (nasab) using ibn or bint, an honorific "father of" or "mother of" name (kunya) using Abu or Umm, and a family, tribal or place name (nisab/laqab). In everyday and business correspondence only the given name and sometimes the family name are used. This guide covers that structure, the honorific used in email, how far gender can be guessed from a name, and a safe neutral form for when you are unsure.
Name order and structure
The ism is the personal given name (Ahmed, Fatima). Ibn ("son of") or bint ("daughter of") introduces the father's name in the full formal chain: Ahmed ibn Yusuf is Ahmed, son of Yusuf. A kunya such as Abu Khalid ("father of Khalid") or Umm Layla ("mother of Layla") is an honorific used instead of or alongside the given name, often by the person's own children's names, and can appear in an email signature as the preferred form of address. Family or tribal names, when present, come last and function closest to a Western surname.
In shortened everyday names, what looks like a middle name is very often the father's given name (a patronymic), not a family name, so a two-word Arabic name is frequently given-name-plus-father's-name rather than given-name-plus-surname.
Honorifics and titles in business email
Arabic business correspondence typically addresses the given name directly with a title: Sayyid Ahmed (Mr. Ahmed) or Sayyida Fatima (Ms. Fatima), the reverse of Western practice where the title attaches to the family name. In English email, "Dear Mr./Ms. [given name]" mirrors this and is standard; "Dear [full name]" without a title is a safe neutral fallback. If a kunya appears in the signature (Abu Khalid), using it is a mark of respect and generally preferred over the given name once you know it.
Gender and names
Grammatical gender marking is more consistent in Arabic than in most languages: many feminine given names end in "-a" or "-ah" (Fatima, Layla, Amina), a pattern that carries fairly reliably into transliteration. Masculine names lack this ending (Ahmed, Omar, Yusuf) but there is no equally consistent masculine marker, so a name that does not end in "-a" is more often, but not always, male. Some names (Nour, Iman) are used for both genders.
What to write when unsure
When gender is unclear, "Dear [full name]," without a title is correct and neutral. Because the "-a" ending is a reasonably strong feminine signal in Arabic, a name ending that way can usually be addressed as Ms./Sayyida with more confidence than in most other naming traditions; names without it are better treated as uncertain rather than assumed male.

Frequently asked questions
What do ibn and bint mean in an Arabic name?
Ibn means "son of" and bint means "daughter of"; they introduce the father's name in the formal name chain, e.g. Ahmed ibn Yusuf, Ahmed son of Yusuf.
What is a kunya?
A kunya is an honorific like Abu Khalid ("father of Khalid") or Umm Layla ("mother of Layla"), often preferred by the person over their given name once you know it.
Should I address someone by their given name or family name?
By the given name with a title (Mr./Ms.), the reverse of Western practice, since Arabic honorifics typically attach to the personal name, not the family name.
Can I guess gender from an Arabic given name?
Reasonably well for names ending in "-a" or "-ah" (Fatima, Layla), which are reliably feminine; names without that ending are more often but not always masculine.
