Definition

1. Adjective:
   • Having an unpleasant smell; malodorous: The word "niffy" is a British informal term used to describe something that emits a bad or offensive odor.

Usage

• "Niffy" is primarily used in casual, spoken British English to comment on an unpleasant smell. It is not appropriate for formal writing or situations.
• It typically functions as a predicate adjective (e.g., "That bin is niffy") or attributively before a noun (e.g., "a niffy smell").

Examples

• Adjective:
  • Take the rubbish out; it's getting a bit niffy in here.
  • After the gym, his trainers were decidedly niffy.
  • What's that niffy odor coming from the fridge?

Advanced Usage

• The term can be used humorously or euphemistically to describe a strong bad smell without being overly harsh or vulgar.
• It can sometimes imply a stale, musty, or sweaty odor rather than a sharply chemical one.
