củ cái

Người nông dân thu hoạch những củ cái từ ruộng.

Definition

1. Noun:
   • A type of yam: "Củ cái" refers to a specific variety of yam (a tuber), botanically distinguished as having a winged stem or vine.
   • Less common term: In modern Vietnamese, this term is considered somewhat archaic or highly specific. The general word for yam is "khoai" (as in khoai mỡ, khoai từ), making "củ cái" a precise botanical or regional term.

Usage Examples

• Noun:
  • Người dân trong vùng trồng củ cái để làm lương thực chính. (The local people grow củ cái as a staple food.)
  • Củ cái có thể được chế biến thành nhiều món ăn. (The củ cái yam can be processed into many dishes.)

Advanced Usage

• Botanical Context: The term is primarily used in botanical or agricultural descriptions to specify this particular yam species (, or winged yam, is a common candidate).
  • Trong phân loại thực vật, củ cái được ghi nhận có thân có cánh. (In botanical classification, củ cái is recorded as having a winged stem.)

Notes on Usage
