• Agrippa — A renowned historical name and masculine given name of Latin origin (Agrippa), famous in Roman antiquity through figures like Marcus Vipsanius Agrippa, general, architect, and son-in-law of Emperor Augustus, or the Judean kings Herod Agrippa I and II. In onomastics, the name is structurally associated with a difficult birth, specifically a breach birth.
• Agrippa — The Latin and international orthographic form for the historical name Agripa. It is borne by outstanding figures of antiquity and later eras, such as Marcus Vipsanius Agrippa (Roman statesman and general), Heinrich Cornelius Agrippa von Nettesheim (Renaissance astrologer and alchemist), or the Greek skeptic philosopher Agrippa, famous for the five tropes or modes used to justify suspension of judgment.
• Violin bow — A regional or obsolete variant for the word 'arcuș' (musical bow); a thin rod of flexible wood equipped with horsehair stretched between its ends, used to vibrate the strings of a musical instrument (violin, viola, cello). In an archaic technical sense, the term could also denote a curved device used in primitive carpentry or turning workshops to impart a rotational movement to structurally machined parts.
• Archetto — A musical term borrowed from Italian denoting a small or slender bow, specifically used for period instruments of the viola family or for executing miniature technical details in Baroque music. In a structural-constructive sense, archetto also represents the elastic bridge or curved tension element that holds the horsehair strands, playing a crucial role in controlling dynamic nuances and sound articulation.
• Archi — A collective musical term used to designate the entirety of bowed string instruments (violin, viola, cello, double bass) within a symphonic orchestra or a chamber ensemble. In a structural sense, the 'archi' section represents the core fundamental sonic nucleus of the classical orchestra, responsible for providing the continuous harmonic texture and timbral richness in orchestral compositions.
• Archiviola — An experimental period musical instrument or hybrid variant of the viola family, structurally equipped with a keyboard and a continuous bowed rotary mechanism (similar to a hurdy-gurdy or viola organista), designed to produce sustained orchestral sounds. In an organological sense, archiviola represents a Renaissance and Baroque attempt to combine the polyphony of keyboard instruments with the timbral richness and dynamic expressiveness of bowed strings.
• Arco — A term used as a direction in instrumental music, instructing performers of stringed instruments (violin, viola, cello, double bass) to resume playing the notes with the bow, following a structural section where the strings were plucked with the fingers (pizzicato).
• Arcșor — A variant form or structural diminutive for the word 'arc' (bow/spring); it represents a small bow, a tiny spring, or an arcușor used for decorative or mechanical purposes, or described metaphorically in classical poetry and urban folklore as the symbolic weapon of Cupid (Amorul). It reflects a rare consonantal and suffixal alternation in the constitution of Romanian diminutive words.
• Small spring — Diminutive of the noun 'arc' (spring/bow); a small-sized mechanical component made of steel or elastic material, structurally utilized in various fine mechanisms (watchmaking, locks, valves) to exert a pressing, returning, or shock-absorbing force. In anatomy and biology, the term can describe minuscule curved structures or concave anatomical profiles.
• Violin bow — An essential accessory for bowed string musical instruments (violin, viola, cello, double bass), consisting of a thin, slightly curved rod of flexible wood or carbon fiber, between the ends of which a bundle of horsehair is tightly stretched. By rubbing the rosin-treated hairs over the strings, the bow sets them into continuous vibration, generating the sound. In engineering, it denotes a lever or a curved elastic piece used to tension primitive mechanisms.
• Small spring — A diminutive for a bow or spring; a very small metallic spring structurally utilized in precision mechanics, watchmaking, locksmithing, or electronic devices to ensure the return of a component to its original position via detensioning. In a musical sense, the term describes a miniature bow used either as a decorative accessory or for toy stringed instruments designed for children.
• Arpeggione — A historical bowed string instrument, similar in size to a cello but tuned like a guitar (six strings) and equipped with frets on the fingerboard, invented in 1823 by Johann Georg Staufer. It is known almost exclusively through Franz Schubert's famous Sonata in A minor for arpeggione and piano, offering a melancholic, hybrid timbre between a classical guitar and orchestral strings.
• Fiddle bow — A regional or archaic term found in certain communities in Transylvania and Banat, used as a phonetic variant for 'arșeu' (bow) or to designate a rudimentary curved tool used in crafts or for guiding threads; (in a folk musical context) an archaic name for the bow of a violin or other traditional stringed instruments. This word reflects structural lexical adaptations specific to cultural interference zones in the west of the country.
• Fiddle bow — A rare regional or archaic form, used in certain Romanian rural communities as a phonetic variant or diminutive derivative for 'arcuș' (the flexible stick with horsehair threads used for playing the violin or fiddle); (in a domestic technical sense) it can describe a small piece of curved wood or a safety element used for the structural fastening of shutters or traditional weaving tools.
