Definition

1. Noun:
   • The visor of a cap: The projecting front part of a cap's brim, typically made of stiff material, that shades the eyes from sunlight.
   • A peak: The stiff, projecting front part of a headpiece, especially on a cap or kepi.

Usage Examples

  • Anh ấy đội mũ lưỡi trai. (He is wearing a peaked cap.)
  • Lưỡi trai bị cong lên. (The peak/visor is curled up.)

Advanced Usage

• The term "lưỡi trai" is almost exclusively used to describe the part of a hat. It is a compound noun, with "lưỡi" meaning "tongue" (referring to the shape) and "trai" meaning "oyster" or "shell" (historically referencing materials or shapes), but in modern usage, it is treated as a single lexical unit for "visor/peak".
• It is commonly found in the compound noun "mũ lưỡi trai" (peaked cap, baseball cap).
