#Greek etymology
- Asyncritus — A masculine proper name of Greek origin (Asynkritos), borne by Saint Asyncritus, one of the Seventy Apostles of Jesus Christ and bishop of Hyrcania. In a historical and religious sense, the name structurally means 'incomparable' or 'unrivaled', being mentioned by Saint Paul in his Epistle to the Romans.
- Asineta — A feminine proper name of Greek origin (Asynethos / Asyneta), historically borne in early Christian hagiography. In a structural and etymological sense, the name is associated with the idea of purity, being encountered as a rare onomastic variant or isolated graphic interpretation in religious databases and Byzantine martyrologies.
- Astro — Initial combining form derived from the Greek 'astron' used to construct words related to stars, celestial bodies, or outer space. Used independently in modern colloquial language, technology, or hobbyist communities, the term designates astrophotography, stargazing equipment, or software platforms optimized for deep-sky imaging processing.
- atacto- — A linguistic combining form derived from the Ancient Greek 'ataktos' (disordered, irregular), used in international scientific terminology (especially in botany, anatomy, and polymer chemistry) to form words designating a structure lacking order, an irregular arrangement of organs, or a chaotic and asymmetrical molecular configuration.
- Abercius — A Romanian masculine given name of Greek and ecclesiastical origin, today rare or archaic, tracking back to the name Aberkios (meaning 'he who restrains, expels, or subdues evil'); it is the name of a 2nd-century holy hierarch (Saint Abercius, Bishop of Hierapolis, the wonderworker). In Romania, it historically circulated primarily within Orthodox and monastic communities, later turning into a fixed surname through patronymic inheritance.
- Eugenia — An archaic or regional Moldavian form of the feminine given name Evghenia (or Eugenia), of Greek origin, translated as 'noble', 'well-born', or 'of distinguished lineage'. The name historically circulated during the 18th and 19th centuries within boyar and ecclesiastical families in Moldavia and Wallachia, preserving a distinguished, literary, and traditional resonance, found today exclusively in archive documents or as a rare surname.
- Avrentie — A proper masculine name of Greek origin (Abrentios / Laurentios), entering Romanian onomastics through religious, Slavonic, and Byzantine channels. Its etymological meaning is linked to the idea of 'bright', 'luminous', or, in other historical interpretations, associated with the ancient city of Laurentum. It is a hagiographic name borne by martyred saints in the Christian Orthodox tradition, which has now become a rare name with an archaic resonance.
- Authentic (archaic) — An archaic, regional form or old phonetic variant of the modern adjective 'autentic' (authentic). Originating from the Greek 'avthentikos' through the Slavonic language in medieval religious and administrative texts of the Romanian space, the term defines a document, object, or testimony whose veracity, originality, and authority are unquestionable, without being altered by falsification.
- Autonomous (archaic) — An archaic, regional form or old phonetic variant of the modern adjective 'autonom' (autonomous). Having entered the Romanian language in the 18th-19th centuries through Greek (avtonomos) or Slavonic channels, the term defines a political, administrative, ecclesiastical entity, or a person enjoying partial or total independence, having the right to self-govern by its own laws, without external interference.
