udDin

udDin is a name element that appears as both a given name and a surname in Muslim-majority regions, particularly within South Asian communities and the Bangladeshi and Pakistani diasporas. It is a transliteration variant of the Arabic element ad-Din, meaning "the religion" or "the faith." In compound personal names, din or ad-Din is combined with other elements (for example Nur-ud-Din, Shams-ud-Din), and udDin may appear as a standalone form or as part of such compounds when written in Latin script. The capitalization pattern in udDin reflects modern transliteration practices rather than a distinct linguistic division; orthographies also render the element as Uddin, Udin, or Ud-Din.

Geographically, udDin is commonly found as a surname among Bangladeshi and Pakistani communities, and it also appears as a given name in parts of India, Afghanistan, and the broader region due to shared linguistic and religious influences. When used as a surname, it is typically gender-neutral in formal records, while as a given name it is traditionally masculine in its conventional usage.

As a name element, udDin is linked to a family of names that celebrate religious identity and cultural heritage. Related forms include Ad-Din, Din, Uddin, and Ud-Din, which appear in various transliterations across languages and regions.
