  • Love Merriam-Webster's app! Thanks!

    By SC from Virginia
    Merriam-Webster’s dictionary app is great for anyone learning English. I especially like synonyms, antonyms, and thesaurus features which give me related words and phrases at every word. This app has clear and high-quality audio pronunciations, sentences, and concise definitions. Also, it nicely displays the parts of speeches. I utilize its favorite feature to save words and study them. Another smart and cool feature is that this app beautifully syncs with my Apple devices. Also, it works offline even though its audio pronunciation doesn’t work. I can add the words to favorite or delete the saved words offline, and once my Apple devices are online, they automatically sync. This app is an excellent dictionary. Kudos to everyone who developed this extraordinary dictionary app; thank you to developers for this awesome app! I love it! The best is yet to come....

    My favorite dictionary and my favorite dictionary app. Unfortunately it doesn’t support Siri Shortcuts but I hope they will add this feature
  • Missing transcriptions in new app

    By rchrdyan
    I do not understand why you decided to “simplify” pronunciation transcriptions in your latest app. For instance, the word kilometer used to have multiple pronunciations in the older version and they are still there in the web version. It will be highly appreciated if you could bring the good old app back.
  • Excellent

  • Jesse Review

    By Jesse gendelman3
    I felt like I’m being intelligent because the more I learn the words the more bigger my vocabulary is. It’s a good app for me. I love it forever.
  • Love this WEBSTER app!!

    By Jekwus
    Love learning new words and their history as well. I like sharing with my prodigy 15 year old niece. Wish I could buy app for her. She is an avid reader and taking college courses. I see a new funny word and share with her. Asking her use in a sentence. So hilarious! So I’m having great time using this app. Seems one can’t pronounce a word if you can’t spell the word.
