Definition

1. Adjective:
   • Slightly rough or coarse to the touch: Describes a surface that is not smooth, having a mild, gritty, or uneven texture.
   • Unpleasant or crude in manner: Used figuratively to describe behavior, speech, or an atmosphere that is somewhat vulgar, uncouth, or lacking refinement.

Usage Examples

• Adjective (Texture):
  • Bề mặt bàn này cảm giác nham nhám. (The surface of this table feels slightly rough.)
  • Giấy giáp loại này rất nham nhám. (This type of sandpaper is very coarse.)
• Adjective (Manner/Quality):
  • Anh ta có lối nói chuyện nham nhám. (He has a somewhat crude way of talking.)
  • Bầu không khí trong quán bar đó hơi nham nhám. (The atmosphere in that bar is a bit vulgar.)

Advanced Usage

• The word often implies a degree that is not extreme; it is rougher than smooth but not as rough as extremely gritty or jagged surfaces (like "gồ ghề" or "sần sùi").
• When used figuratively, it suggests a lack of polish or tact, but not necessarily deeply offensive behavior.

Variants and Related Words

• Nhám (adj): Rough, abrasive. This is the root word from which "nham nhám" is derived, often implying a more standard or technical roughness.
  • Mặt nhám giúp tăng độ bám. (A rough surface helps increase grip.)

Synonyms

• Rough: Having an uneven or irregular surface.
• Coarse: Rough in texture, composed of large particles.
• Gritty: Containing or resembling grit; rough.
• Unrefined: Lacking elegance or polish (for figurative use).

Related Idioms

• While "nham nhám" itself is not typically part of a fixed idiom, its figurative use conveys a similar idea to the English phrase "rough around the edges," describing a person or thing that is fundamentally good but lacks sophistication or polish.
