Arsini / Arsenios / Arseniy / Arsen

The name Arsini is a variant of Arsenios, which is derived from the Greek word 'arsen' (ἄρσην), meaning 'masculine' or 'virile'. It has historically been used as a male name, particularly in Eastern Orthodox Christian traditions. The feminine form, Arsenia, also exists, and 'Arsini' can sometimes be a diminutive or a regional variant used for both genders, though its root is distinctly masculine.

Its usage is more prominent in regions with strong Greek or Slavic Orthodox influences. While primarily a male name in its original forms, the 'i' ending in some languages can sometimes lead to its adoption as a unisex or even feminine name, though this is less common than its masculine use. The name carries connotations of strength and manliness due to its etymology.
