#linguistic suffix
- Anculescu — A Romanian patronymic surname, distributed primarily in the historical regions of Muntenia and Oltenia, structurally formed on the onomastic radical Ancu. The specific suffix indicates direct descent, meaning 'the son of Ancu', reflecting a classic model of family name stabilization in Romania whereby parents' nicknames or first names became hereditary identity marks.
- Andonin — An extremely rare Romanian surname or archaic masculine first name, structurally composed of a hypocoristic root related to Andonie or Andrei and extended via the popular diminutive suffix '-in'. It represents an old onomastic variant preserving dialectal features specific to isolated rural communities in the Balkan basin.
