#arcs
- Arches — The plural form of the neuter noun 'arc'; curved structural or decorative elements supported by two endpoints, used in architecture to span a space or support a vault or wall. In geometry, it represents continuous portions of curved lines, especially of circles, bounded by two distinct points. In music and engineering, it refers to springs acting as elastic mechanisms or bows used for stringed instruments.
- 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.
