dictionary

A dictionary is a reference book or online resource that contains a list of words from a language, along with their meanings, pronunciations, and usage. It helps users understand the definitions of words, how to pronounce them, and how to use them in sentences. Dictionaries also often include information about word origins (etymology), synonyms (words with similar meanings), and antonyms (words with opposite meanings). They are valuable tools for improving vocabulary, enhancing communication skills, and aiding language learning.
