ahlan

Ahlan is an Arabic interjection used as a greeting meaning hello or welcome. It is widely used across the Arab world and in Arabic-speaking communities worldwide. The expression is most commonly heard in the longer formula ahlan wa sahlan, which literally translates as "a welcome and an easy arrival" but is understood simply as "welcome" or "you are welcome." Ahlan can be used on its own as a casual greeting or in response to a greeting or introduction.

Usage varies by context and region. Ahlan is typically informal and friendly, suitable among friends, family, or guests. In more formal situations, speakers may choose marhaba (hello) or the fuller ahlan wa sahlan for hospitality. Another common form is ahlan bik or ahlan bikum, meaning “welcome to you” or “welcome to all of you,” depending on the addressee. Dialectal pronunciation and transliteration can differ, but the basic function remains the same.

Etymology and cultural role: Ahlan derives from the Arabic root ahl, meaning people or family, reflecting a cultural emphasis on hospitality toward guests. The greeting conveys warmth and sociability and is a staple in everyday conversation, signage, media, and online communication across Arabic-speaking communities and the Arab diaspora. Variants and related phrases coexist with regional nuances in formality and tone.
