Definition

1. Adjective:
   • Separated or disconnected: Used to describe things that are set apart, not joined, or lacking a clear connection.
   • In statistics/biology: Referring to a distribution where populations or occurrences are geographically separated and not continuous.
   • In music: Describing a melodic progression that moves by large intervals (larger than a major second), creating a disconnected or leaping sound.
   • In zoology: Having the body parts (like head, thorax, abdomen) deeply constricted and distinctly separate, as in some insects.

Usage and Examples
