#matronymic

• Adăniloaei — A Romanian surname of a matronymic type, particularly specific to the historical region of Moldavia (and Bukovina), formed from the masculine given name Dan (or Danilo) via the name of the wife or mother (Dăniloaia). This name reflects an old linguistic and social custom where children received the feminine derivative of the father's given name as a surname if the mother became a widow or the head of the household.
• Afloarei — Romanian surname predominantly found in the historical region of Moldavia. Structurally, it is a matronymic name formed by merging the preposition 'a' (indicating lineage or belonging) with the inflected genitive form of the feminine noun 'floare' (Floarea), originally signifying the son or descendant of a woman named Floarea.
• Androae — An archaic matronymic form or rare regional appellative used in traditional Romanian rural communities to designate the wife, daughter, or descendants of a person named Andru, Andraș, or Andrei. In a linguistic and structural context, this term reflects traditional onomastic derivation mechanisms where a woman's social identity was correlated with the family leader's name.
• Aoncioaei — A Romanian surname, rare and regionally specific, predominantly found in the historical areas of Moldavia and Bukovina. It belongs to the onomastic category of matronymics, formed through a popular derivation indicating maternal descent from a woman known in the community as Anca or Oana, via local phonetic transformations specific to the eastern dialect.
• Aonofriesei — A Romanian surname with a pronounced regional character, frequently encountered in the historical area of Moldavia. From an onomastic point of view, it is an archetypal matronymic formed in rural environments, indicating direct maternal descent from a woman named Anofriza or the wife of a man named Onofrei, structured through phonetic modifications specific to the Moldavian dialect.
• Asandei — A patronymic variant of the Romanian surname Asande, stabilized in civil records through the addition of the specific feminine genitive-dative ending or through direct matrilineal or patrilineal filiation (originally meaning 'of Asanda' or 'the son of Asanda'). It is a surname very frequent in the Moldavian region, reflecting the traditional way rural communities identified individuals by their mother's name or a prominent family in the village.
• Asmarandei — A Romanian surname epidemiologically derived from a maternal genitive form (matronymic), originally meaning 'of Smaranda' or 'Smaranda's son'; it is currently used as a fixed family name, encountered with a higher frequency in the historical region of Moldavia.
• Astancai — A rare Romanian surname, primarily encountered in the historical region of Moldavia; a matronymic derivative formed by attaching the popular genitive suffix '-ăi' to the feminine given name Stanca, with an archaic vocalic prosthesis 'A-'. It also functions as a local microtoponym denoting a former estate, clearing, or watercourse historically owned by a woman bearing this name.
• Avărvarei — A Romanian surname formed through matronymic blending, specific to the historical regions of Moldavia and Bukovina. It originally indicates descent from a woman named Varvara (meaning 'of Varvara'), a feminine given name of Greek origin meaning 'foreign' or 'barbarian', frequently used in Christian Orthodox onomastics due to Saint Barbara. The addition of the popular phonetic prefix 'A-' reflects a regional dialectal feature of transmitting lineage through the maternal line.
• Avastiței — A Romanian surname, with a specific prevalence especially in the historical region of Moldavia, formed through a matronymic process. It originally indicates descent from a woman named Vastița or Avastița, an old feminine given name, rarely found today, which is derived as a hypocoristic or diminutive form from the biblical name Vashti (a character from the Book of Esther).
