Love this app

I stumbled across the Word of the Day a few years ago, and was getting it in my email every morning. I word share it on social media every day. But then it stopped coming. Seriously, MW, what’s up with that? I checked my spam folder, I tried unsubscribing and then subscribing again, but nothing. It just would not send. (I know...this doesn’t really seem like a 5 star review, does it? Stay with me, it gets better. 😂)

But finally it dawned on me that I was using the website a lot to look up words, either in the dictionary or the thesaurus, and that I should just look for the app. Hey, I’m 62 and a little slow with technology, OK? I love the app, and I use every day...usually several times a day. I look up meanings of unfamiliar words, of course. But I use the thesaurus a lot. When I am writing an email, or text, or posting on social media I frequently find myself searching my brain for a word that I know is perfect for the context, but my brain just can’t seem to grab onto. (Old and slow, remember?) I go to the thesaurus and start putting in words that are similar, but not quite what I’m looking for. Most of the time, I find the word I want. Occasionally I don’t, but I do find an acceptable substitute.

I still check out the WOD, and share it on social media. And I am absolutely LOVING the way they subtly (and sometimes not so subtly) throw shade at the current President and administration. It’s a master class in shade throwing. 😎😂

Love love love this app, misspelling and grown people not knowing how to use verbally or written English drives me crazy. Therefore I drive people crazy. I’m Native America, knowing about our history and how our Native language was stolen makes me even more determined to speak and write English correctly. I will never understand the white man trying to assimilate us into their culture, making us learn their language yet they couldn’t even teach us how to speak and write it properly. I get so tired of hearing people make fun of us and how we talk. I’ve often wondered if we had to learn English because the invaders wasn’t smart enough to learn our language. Thank you so much for this wonderful app. I just wished more people used it. It is awesome!!!
I live in NC, so I talk with that old southern draw, but for some reason we Lumbee still have a way of speaking the southern dialect a little different than other southerners even here.
I don’t care where I go people want to hear me talk, or we can be in a different part of NC, well for that matter anywhere in the USA away (Robeson County NC), someone will hear us or we’ll here them and it’s on…!! @“Hey cuz you from RobesonCounty?” “Where you from and whose yer people?”
Anyhow I love home and my “people.” I hope it never changes, every country, state and city needs to learn and keep alive the things that keeps them interesting, different and unique. 🪶🦅

Great, and Helpful, App

I’m still in school, so something like a portable dictionary can be really handy. Though I don’t pay for the premium so I can’t look up everything(especially names) it’s still extremely helpful. Sometimes I hear this strange word on TV or see it in a novel I’m reading and wonder what it is. Sometimes I’m doing school and something asks for the exact definition of a word. Instead it trooping to my basement and flipping for ages through gigantic, long, make your eyes bleed pages, I turn to my phone charging behind me and switch on this app. I’m also a small time writer, so the thesaurus is REALLY helpful when looking for that just right word to fit your story and writing style.
I also love the quizzes-they’re really unique and honestly do teach me words. It’s a little tempting slice of the Quissitive app. I can’t wait until next week’s comes out.
This also very easy to navigate, and everything is clear and concise-so if your not sure you want to use some electronic confusing dictionary, never mind that. Webster is just a few clicks and you’re to your definitions, and one more easy to see button will lead you to the thesaurus. Making an account is easy too!
Great app overall; It’s helped me a ton through school, writing, and my endeavors to increase my vocabulary. Thanks, Merriam Webster! No complaints here on my part.
