Definition

1. Noun:
   • Tegmen (Botany): The inner, thin, membranous layer of a seed coat, specifically the delicate inner integument that surrounds the embryo. It is often contrasted with the outer, harder seed coat (testa).
   • General Meaning: A thin, papery, or membranous shell or husk. While "vỏ lụa" is a technical botanical term, it can be used descriptively to refer to any similar delicate, skin-like covering.

Usage Examples

• Noun:
  • Hạt này có hai lớp: vỏ cứng bên ngoài và vỏ lụa mỏng manh bên trong. (This seed has two layers: a hard outer shell and a delicate inner tegmen.)
  • Hãy bóc lớp vỏ lụa của hạt đậu phộng trước khi ăn. (Peel off the thin skin of the peanut before eating.)

Advanced Usage

• In botanical descriptions, "vỏ lụa" is a precise term for the tegmen.
  • Vỏ lụa thường dễ bị bong ra khi hạt khô. (The tegmen often easily peels off when the seed is dry.)

Variants and Related Words

• Vỏ hạt (n): seed coat, testa (a more general term for the seed covering).
• Màng (n): membrane, thin film (a broader term for similar delicate layers).

Synonyms

• Inner seed coat: A descriptive synonym in botany.
• Tegmen: The direct technical synonym.
• Membranous husk: A general descriptive synonym.

Notes

• "Vỏ lụa" is a compound noun where "vỏ" means "shell/peel" and "lụa" means "silk," poetically describing the layer's thin, smooth quality. It is primarily used in scientific or detailed descriptive contexts rather than everyday conversation.
