Idioms classify into distinct types based on structure and function. The primary categories include:
- Pure Idioms: Fixed phrases with meanings that differ from literal words (e.g., “kick the bucket” signifies dying).
- Binomial Idioms: Paired expressions linked by conjunctions (e.g., “back and forth” indicates alternating movement).
- Simile Idioms: Comparisons using “as” or “like” (e.g., “as busy as a bee” describes extreme busyness).
- Proverbial Idioms: Short sayings that convey traditional wisdom (e.g., “a stitch in time saves nine” advises prompt action).
- Partial Idioms: Expressions blending literal and figurative meaning (e.g., “spill the beans” means to reveal a secret).
A 2020 study from the University of Warwick’s Department of English Language reports these categories represent varied portions of idiomatic usage in modern English.
