Definition

Noun: A specialized reference work that provides the historical origins and development of individual words, tracing their roots through different languages and time periods to show their earliest known forms and meanings.

Usage

An etymological dictionary is used for academic research, linguistic study, or personal curiosity to understand where words come from and how their forms and meanings have changed. - It focuses on the etymology (word history) rather than just current definitions, pronunciations, or usage. - Entries typically show a word's progression from its oldest known root (e.g., in Proto-Indo-European, Latin, Old English) to its modern form.

Examples

Advanced Usage
