tai hồng
Definition
- Noun:
- Wing nut: A type of fastener (nut) with two flat, wing-like projections. These wings allow it to be easily tightened and loosened by hand without the need for a wrench. It is commonly used on the axle of a bicycle wheel.
Usage Examples
- Noun:
- Vặn chặt tai hồng để cố định bánh xe. (Tighten the wing nut to secure the wheel.)
- Tai hồng trên xe đạp cũ của tôi bị gỉ. (The wing nut on my old bicycle is rusty.)
Advanced Usage
- The term is a compound noun specific to technical and mechanical contexts, primarily for bicycles. In broader engineering, the general term "écrou papillon" (butterfly nut) or "écrou à oreilles" (eared nut) is used in French, which directly corresponds to the Vietnamese "tai hồng" (pink/pale ear, referring to the wing's shape and color on some models).
Variants and Related Words
- Đai ốc tai hồng (n): A more formal or descriptive term meaning "eared nut" or "wing nut."
- Ốc vít (n): Screw; a general term for threaded fasteners.
Synonyms

- Thumb nut (a similar nut designed for hand-tightening)

Notes on Different Meanings
- The term "tai hồng" is highly specific to mechanics. It is not to be confused with the literal, separate meanings of its components: "tai" (ear) and "hồng" (pink, rosy). In this compound, "hồng" likely refers to a pale or metallic color, not the color pink.
