Definition

1. Adjective:
   • Congenital, connate: In botany, describes plant parts (especially leaves) that are fused or united from birth or from their earliest development, appearing as if grown together.
   • Coadnate: A technical botanical term meaning fused or attached to another part, typically referring to structures like stipules attached to a petiole, or anthers attached along their whole length to the filament.

Usage Examples

• Adjective:
  • Lá đài hợp sinh là đặc điểm của nhiều loài thực vật. (The sepals are connate, which is a characteristic of many plant species.)
  • Trong hoa này, các nhị hợp sinh với nhau. (In this flower, the stamens are coadnate to each other.)
  • Các cánh hoa hợp sinh tạo thành một ống. (The petals are connate, forming a tube.)

Advanced Usage

• This term is almost exclusively used in specialized contexts, particularly botany and biology, to describe the morphological fusion of similar organs. It is not used in everyday conversation.
• "hợp sinh" vs. "dính liền": While both can imply fusion, "hợp sinh" specifically refers to a natural, congenital fusion from development. "Dính liền" can be a more general term for being stuck or adherent, which may or may not be congenital.

Variants and Related Words

• Hợp (verb): To combine, to unite.
• Sinh (verb): To be born, to grow.
• Hợp nhất (verb): To merge, to unify (more general, not specific to biology).
• Dính liền (adjective): Adherent, conjoined (can be used in both general and biological contexts).

Synonyms

• Dính liền bẩm sinh: Congenitally adherent.
• Kết dính: Adhesive, sticking together (less specific to natural growth).

Notes on Meaning

• Primary Meaning: The core meaning is "congenitally fused". It describes a state of being joined that is inherent from the organism's development, not a result of later adhesion or disease.
• Field of Use: This is a technical/scientific term. Its use outside of botany, biology, or possibly medicine (to describe certain congenital conditions) is extremely rare.
