Definition

1. Noun:
   • A grass-like or rush-like plant that typically grows in wet or marshy areas. Sedges are characterized by having solid, triangular stems (in cross-section), narrow grass-like leaves, and small, often inconspicuous flowers arranged in spikelets. They are a key component of many wetland ecosystems.

Examples of Usage

• Noun:
  • The wet meadow was dominated by various species of sedge.
  • Sedge provides important habitat and food for many wetland birds.
  • You can distinguish a sedge from a grass by feeling its solid, triangular stem.

Advanced Usage

  • We heard the distinctive song of a sedge warbler in the reeds.

• "Sedge meadow": A type of wetland community where sedges are the dominant vegetation.

Variants and Related Words
