#old onomastics
- Algu — An extremely rare proper noun used historically in local onomastics or toponymy. In medieval documents or old parish registers, it appears sporadically as a hypocoristic masculine given name or as a minor name for isolated watercourses, acting as a preserved archaism.
- Azbine — An archaic onomastic form, regional graphic variant, or historical toponym of restricted circulation within the Eastern European or Balkan area, structurally derived from an old stock of proper names or local phonetic adaptations. In old administrative documents, the term served as an individual identity mark or as a microtoponym designating an estate or settlement historically linked to a certain family patronymic line.
