Definition

1. Verb (idiomatic, informal):
   • To begin to sprout (a negative trait): To unexpectedly develop or display a bad habit, vice, or undesirable characteristic that was not present in one's ancestors or family lineage. It implies a sudden, surprising emergence of a flaw that seems alien to one's heritage.

Usage Examples

• Verb:
  • Cả nhà ai cũng hiền lành, chỉ có nó mới nảy nòi hung dữ như thế. (Everyone in the family is gentle; only he has begun to sprout such violence.)
  • Sao thằng bé lại nảy nòi hung dữ thế? (Why has the boy begun to sprout such fierceness?)

Advanced Usage

• The term is almost exclusively used in a negative, critical, or surprised context to comment on the incongruous appearance of a bad trait in an individual compared to their family background.
• It often carries a tone of disappointment or bewilderment.

Word Origin and Nuance

• The phrase combines "nảy" (to sprout, to spring up) and "nòi" (breed, lineage, stock). The literal image is of a bad trait "sprouting" from an otherwise good "stock," highlighting its unexpected and unwelcome nature.
• It specifically refers to non-hereditary defects, emphasizing that the trait is not inherited but has appeared anew in the individual.

Synonyms

• To develop (a bad trait): To begin to have or exhibit.
• To manifest unexpectedly: To appear suddenly and surprisingly.
• To contract (vices) (as used in the French reference): To acquire, especially something undesirable.
