Definitions

1. Expletive/Particle (Thán từ/Trợ từ):
   • A vulgar intensifier expressing strong negation, disregard, or emphasis: Used to completely negate a statement or express absolute indifference, often with a rude or coarse tone. It is a phonetic variant of "đếch".
   • Not a bloody damn, not a single bit: Serves as a strong, vulgar negation, equivalent to "not at all" or "hell no" in English, but more offensive.

Usage Examples

• As an intensifier for negation:

  • Tao đách biết! (I don't fucking know! / I don't have a bloody clue!)
  • Đách quan tâm! (I don't give a damn! / I couldn't care less!)
  • Nó đách đến dự đám cưới. (He didn't bloody show up to the wedding.)

• Used with "cần" (to need) for strong refusal:

  • Đách cần! (I don't need it one bit! / I don't bloody need it!)

Advanced Usage Notes

• Register and Tone: This word is highly vulgar (tục) and belongs to the lowest register of speech. It is used in very informal, coarse contexts, often among close friends or to express extreme anger, frustration, or defiance. It is inappropriate in formal, polite, or public settings.
• Grammatical Function: It typically precedes and negates the main verb (e.g., , ). It cannot stand alone as a sentence.
• Phonetic Variant: "Đách" is a common northern Vietnamese phonetic variation of the vulgar particle "đếch". Their meaning and usage are identical.

Variants and Related Words

• Đếch (expletive): The more standard spelling of the same vulgar negation particle. Meaning and usage are the same as "đách".
  • Tao đếch hiểu gì cả. (I don't understand a damn thing.)
• Đéo (expletive): Another, even stronger and more common vulgar negation particle. "Đách/đếch" is sometimes considered a slightly softened or regional variant of "đéo".
  • Tao đéo đi. (I'm fucking not going.)

Synonyms (with register notes)

• Không (phủ định): Not. (Neutral, standard negation).
• Chẳng: Not, nary a. (Literary or slightly emphatic, but not vulgar).
• Đâu có: Not at all. (Informal, emphatic negation, not vulgar).

Related Phrases/Idioms
