Simply the best
This is the only online dictionary I use or recommend. It has so many (free) ways to help people expand their vocabulary, and these extras work for high school & college, to writing for personal reasons. That’s the extra that I use, and love, the most; the common synonyms & antonyms, but also M-W includes a lot much more. The one that’s best for me & my writing is the origin of the words, including the approximate historical date (in centuries) in which the word was “created” and who most likely created it. At times I find that the original meaning (as used when it was created) is very different to the present day meanings!
I went ahead & bought the pro-version, as I use it so often in my writing. I’ve found that M-W the dictionary to be the most user friendly, & helpful. Apologies, but I don’t remember how much is was. I only remember that it wasn’t very much.
Just try it, (even the free version still has almost all the things I’ve mentioned.) use it for awhile & compare it to the other online dictionaries. I’m confident that you’ll pick, & stay with, the Merriam-Webster dictionary. 👍🏼
M-W Defends The English Language
I switched from the Oxford dictionary app I previously had for what might appear to be political reasons yet is actually a non-partisan one: defense of word definitions. When President Trump began tweeting out non-sensical statements that twisted or hollowed out the very meaning of certain words he was trying to use in an Orwellian manner, M-W would tweet out a response that focused on the actual definition of the word in defense of meaningful language. It may have appeared partisan to some, but to me it was a simple & timely reminder that words are not empty vessels. They are not window dressing. They are the window itself and attempts to use them to communicate in a way that is deliberately counter to their actual meaning effectively gaslights an entire language & the very culture that relies on it. I am happy with the app, & even happier supporting a company that recognizes that defending the meaning of words is to defend its core reason for being. Thank you M-W.
Love Merriam-Webster's app! Thanks!
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....
