- Achromatism — A secondary or historical graphic and spelling variant of the term 'acromatism'; it defines the structural property of an optical system to transmit white light beams without splitting them into parasitic chromatic components. In older technical texts or 19th-century manuscripts, it represented the transcription standard before modern terminological standardization.
- Archaic admiration — An obsolete and literary form of the word 'admirație', widely used in 19th-century and early 20th-century Romanian literature to denote the feeling of esteem, pleasant wonder, and deep respect. It retains the classical Latin etymological suffix, being found today only in reeditions of classic texts or used intentionally to give a solemn, archaic, or ironic tone to the discourse.
- Archaic admission — An obsolete, legal, or literary form of the act of admitting and its result; acceptance, admission, or permission of a person into an institution, an association, a school, or a professional body; official recognition of a right or a state of affairs. Frequently used in 19th-century administrative jargon, this form has been replaced in modern usage by 'admitere' or 'admisibilitate'.
- Archaic admonishment — An obsolete and literary form for a reprimand, scolding, chiding, or formal warning; the act by which an administrative or ecclesiastical authority drew someone's attention to a moral fault or a breach of regulation. Widely used in legal and administrative texts of past centuries, the term was gradually replaced in modern usage by 'admonestare' or 'avertisment'.
- Archaic admonition — An obsolete, legal, and literary form of the word 'admoniție'; a written reprimand, verbal scolding, or formal warning addressed to a person by a hierarchical authority following an administrative or moral fault.

- Brass-colored — Obsolete spelling variant (using internal 'î' according to pre-1993 orthographic rules) for 'alămiu'; having the color of brass, being of a bright reddish-yellow or greenish-yellow with metallic reflections specific to the copper-zinc alloy. It is used in older literary, technical, or academic texts to describe the warm shade of patinated metal objects or the specific light of the sunset.
- Alcoran — An obsolete and literary spelling variant for the Quran (the holy scripture of Islam). The term was historically used in European and Romanian cultural spaces, influenced by Western languages, keeping the Arabic definite article incorporated directly into the lexical structure of the word, but its current usage is strictly historical.
- Alcove frequenter — An extremely rare archaic or literary term, sometimes used in the past as a mistaken variant for alcove or to describe a person who frequents alcoves, suggesting a gallant, courtly, or boudoir lifestyle. In ancient literature, the word could carry a connotation related to amorous intrigues at princely courts.
- Alimentation — Archaic or formal variant for alimentație, used in legal, medical, or administrative texts from the 19th and early 20th centuries. It structurally describes the same process of feeding, supplying, or maintaining, currently serving as a stylistic indicator of legacy language.

- Anarchism — A neologic or etymological spelling variant for the word 'anarhism' (anarchism); a political and philosophical doctrine based on the complete rejection of any form of institutionalized authority, enforced hierarchy, and state control. It advocates for the organization of society exclusively through free, voluntary associations, mutual cooperation, and self-governance, holding that the state and its coercive structures are inherently oppressive and unnecessary for individual and collective freedom.
- Historical animation form — An archaic, literary, and etymological variant of the noun 'animație', used in legal, literary, or administrative texts of the 19th and early 20th centuries.

- Apica — A rare, archaic, or regional form (sometimes encountered as a phonetic variant or tolerated error) denoting a small opening, a tip, or a sharp structure; used sporadically in folk vocabulary or early technical translations. In current literary Romanian, the term lacks a stable autonomous usage.
- Applause — An old etymological form or direct graphical variant for the neuter noun 'aplaos'; it represents the physical act and public manifestation of clapping hands as a sign of esteem, reverence, or deep approval.

- Application — An archaic form or historical lexicographical variant for the feminine noun 'aplicație'; it represents the action of putting into practice a law, a theoretical principle, an administrative method, or a legal punishment.

In ancient administrative documents and local dialects south of the Danube, the term designated a man of public authority, a high boyar, or a feudal administrator responsible for judging local disputes.
