   • Specifically in botany: Describing leaves that have a wrinkled or ridged surface texture.

Usage

• The word "rugose" is a formal, descriptive term used primarily in scientific contexts, especially in botany, biology, and geology.
• It is used to describe the physical texture of an object's surface.
• It functions as an adjective and typically comes before a noun (e.g., a rugose leaf) or after a linking verb (e.g., The surface is rugose).

Examples

• General Use:

  • The old man's hands were rugose from years of hard labor.
  • The fossil exhibited a rugose texture, indicating its age and the conditions of its preservation.

• Botanical Use:

  • The plant is easily identified by its dark green, rugose leaves.
  • Botanists noted the rugose character of the leaf epidermis under magnification.

Advanced Usage

• "Rugose" can be used in a comparative or superlative form: more rugose, most rugose.
  • The skin on the fruit became more rugose as it dried.
