A dictionary is a collection of words and their definitions, often arranged alphabetically. It is a reference that helps people find the meaning of words they are unfamiliar with. A dictionary can be printed in book form or accessed electronically on computers, tablets, or smartphones. Dictionaries typically contain information about pronunciation, part of speech, etymology (the origin of words), synonyms (words with similar meanings), and antonyms (words with opposite meanings). They may also provide examples of how to use the word in a sentence. Dictionaries often have supplemental material such as biographical and geographical information for proper nouns. The earliest dictionaries were written in the mid-1400s and contained only Latin words. Modern dictionaries include words from many languages including English, Spanish, French, German, Italian, Mandarin Chinese, and more. They can be general or specialized for certain fields such as law or medicine. Dictionary entries usually start with a headword—a main entry word—which appears in bold type at the beginning of the entry. After that is a brief definition followed by any other relevant information such as pronunciation guides, etymological roots, synonyms/antonyms and examples showing usage in sentences. Dictionaries can be found in almost every language and dialect around the world; they are helpful tools for learning new languages and enriching vocabulary skills. They are also invaluable resources for writers seeking to craft effective prose by choosing precise words to convey their ideas clearly and accurately.
