What Is Dictionary.com?

Updated

Dictionary.com is a free online English dictionary you can use in a browser to look up word meanings, definitions, synonyms, word origins, and example sentences. It suits general English readers, students, and writers who need a quick reference, plus anyone interested in word games and daily vocabulary features. The site describes itself as "the world's leading online dictionary" and says it has been a trusted authority for 25+ years.

What you can look up

The core function is straightforward: enter a word and get its meaning. Around that, the site bundles several related resources:

  • Definitions — the primary meaning lookup for English words.
  • Synonyms — alternative words with similar meaning.
  • Word origins — where a word came from and how it developed.
  • Example sentences — the word used in context.
  • Word games — interactive puzzles, including a "Word Puzzle" where you create as many words as you can.
  • Word of the Day — a featured word with pronunciation and definition, for example "behindhand [bih-hahynd-hand]."
  • Trending Words — currently popular terms with short explanations, such as "wepa," "aromantic," "meme stock," and "Lunar New Year."
  • Featured articles — longer reads on language topics, such as the origin of "achoo" and why people say "bless you," weekly news roundups, and writing contests.

How to use it

  1. Open dictionary.com in a browser.
  2. Type the word you want into the search field and submit it.
  3. Read the definition entry, then check the synonyms, origin, and example sentences if you need more context.
  4. Optionally browse Word of the Day, Trending Words, or the games section for vocabulary practice.

The expected result is a definition page for your word, or a list of matching entries if the spelling is ambiguous.

What to keep in mind

  • The site is a general-audience reference, not a specialized technical or legal dictionary.
  • Trending Words and featured articles reflect current usage and editorial picks, so they change over time.
  • The available page information does not state pricing or login requirements, so treat access terms as something to confirm on the site itself rather than assuming.
