Dorjsürengiin

Dorjsürengiin is a Mongolian patronymic surname, meaning 'of Dorjsüren'. In Mongolian naming conventions, the father's (or sometimes mother's) name is often used as a patronymic, followed by a genitive suffix like '-iin' or '-yn'. This indicates lineage and is akin to 'son of' or 'daughter of' in other cultures, though it functions as a surname rather than a given name component.

The name Dorjsüren itself is a compound Mongolian name. 'Dorj' (Дорж) is a common element in Mongolian names, derived from the Tibetan 'dorje' (རྡོ་རྗེ་), meaning 'thunderbolt' or 'diamond', symbolizing indestructibility and spiritual power, often associated with Vajrayana Buddhism. 'Süren' (Сүрэн) means 'protection' or 'guardian'. Therefore, Dorjsüren means 'diamond protection' or 'thunderbolt guardian'. The addition of '-iin' makes it a possessive form, signifying belonging to someone named Dorjsüren.
