Definition

1. Adjective:

   • Having a raw, green, or immature taste/smell: Describes a substance, often tobacco, tea, or certain foods, that has an unpleasant, slightly acrid, or "green" flavor or aroma because it has not been properly aged, cured, or fermented.
   • Slightly acrid or harsh: Refers to a sensory quality that is not yet smooth or mellow.

2. Adverb (in reduplicated form):

   • Slightly raw/green: The reduplicated form "ngai ngái" indicates a diminished degree of the raw or immature taste or smell.

Usage Examples

• Adjective:

  • Chè này vị còn ngái. (This tea has a raw, immature taste.)
  • Thuốc chưa ủ kỹ, hút còn ngái. (Tobacco that hasn't been fermented properly still tastes harsh/green when smoked.)

• Adverb (reduplicated form):

  • Mùi thuốc mới ngai ngái. (The new tobacco has a slightly raw smell.)

Advanced Usage

• The term is primarily used in the context of assessing the quality and readiness of agricultural or processed products like tobacco, tea, betel, or certain fruits. It indicates a lack of proper processing.

Variants and Related Words

• Ngái (noun): Refers to the hispid fig tree (), a species in the fig family. This is a different, though homonymous, word.
  • Lá cây ngái. (Leaves of the hispid fig tree.)

Synonyms

• Raw: Not processed or matured.
• Green: Unripe or not properly aged (in context of taste).
• Acrid: Unpleasantly sharp or bitter in taste or smell.
• Harsh: Rough to the senses.

Notes on Meaning

• The adjectival meaning related to taste is the most common in modern usage.
• The nominal meaning (hispid fig tree) is a separate lexical item that shares the same pronunciation and spelling.
• In some regional dialects, "ngái" can colloquially mean "far" or "distant," but this usage is not standard in the mainstream language.
