LOVE. THIS. APP!!!

I use this app absolutely every day! If I’m in a meeting, or even just having a conversation with someone, and they use a word I’m not familiar with, I’ll make a mental note of it, or jot it down, and as soon as I have a chance, I immediately pull up this app and look up any words I made a note of. I do the same thing when I’m watching TV and any new or unfamiliar words come up... I press pause, and pull up the word in my amazingly handy and convenient Dictionary app! 😁💁🏼‍♀️ This is one of the most substantial and most frequently used apps I have, and I ALWAYS go for any upgrade they offer, which I reallyyyy COULD NOT RECOMMEND MORE! One of my FAVORITE things about this app is the *Learners* tab, which you can click on, especially if the definition is somewhat vague or unclear, and I’d say a good 70-80% of the time, at least, they have a break down of the meaning of the word, how to use it, and how to incorporate it into a sentence, etc~ which is incredibly valuable when you’re just beginning to learn and understand a word and how to use it. I just love it!!! Inevitably, I will continue on to the *Example Sentences* tab to see how the word is further used in different ways and contexts, which is also extremely helpful. It’s always surprising to me how much use I get out of this app, but it has helped me immensely to expand my vocabulary, and for that, I’m extraordinarily grateful. I wish I could give this app 10 stars!!! ✨⭐️🌟

Dictionary of the day is awesome!

Dictionary of the day is an effective and fun way to easily increase your vocabulary or remind you of words that might have slipped your mind over the years or for that moment when you are distracted and do not want to wake up slapping your forehead at 3AM. Also, one of the biggest benefits is that I am usually able to sneak in at least 3-5 other new/remembered words after reading the daily one. This is why I initially got the app. However, after now using this Dictionary app every day over the course of years; I have found it to be helpful, efficient, easy to use and can be fun and diverting. The reasonable price is the cost of an high calorie, high cholesterol, fattening and unhealthy CappaFrappaAnywayYouLikeItCino and once you enjoy that drink it will be gone forever. But this wonderful Dictionary/Thesaurus with all of it’s content will be with you forever. Considering other options that I have personally used; such as MW, et. al., I most highly recommend this app.

Vocabulary is Power

Mark Twain advised ; “Never argue with a stupid person, they will only drag you down to their level and then beat you with experience.”
I use the Dictionary app every single day, no kidding. To take quizzes, learn the difference of and the correct way to use words. Word of the day is awesome and in my morning email daily. Pretty cool right? The videos are clear concise and often humorous making learning fun. Sometimes I am little shocked by the subject/content of the articles/videos ie; (or is it eg;?) lol
Topics of sex & sexuality, rec. drugs I kinda think “whoa” however by all accounts they’re current, relevant and educational. The other apps associated with Dictionary are fantastic also! Using the same or similar format makes them easy to navigate from day 1. I have this app 5 stars because they didn’t offer any above that.
