Scarlet Pimpernel

Periodically I read and of course some of the things I read aren’t always fully understood by myself. Today I am reminiscent of a past I had known for love of life itself and to help stand up even if not asked. At times we must do things that lead us down paths that might be better suited for a Knight of more distinguished honor and than oneself. Being truly humbled by such a vast amount of the English languages which has included many slang terminologies. Having forgotten many things I find myself coming back to attempt to concrete things in my mind and yet life has been nothing less than an amazing journey from reading hardback books flipping endlessly through pages to this day of technology in which I write this review on my cellular phone. I am a simple man but humbled by having found a great dictionary that has rekindled my intrigue concerning reading and keeping things such as this dictionary in a safe place so as to always have if nothing else, a memory of a dream and then being reminded that we must always strive for better things and through that, Growth Through Knowledge and understanding.

A truly great dictionary.

I have had this dictionary since 2016. I am impressed with its coverage of all words. If you have misspelled a word, it gives you several options of the word you might be looking for. It also will give you the derivation of the word: did it come from old French or another language. It will also give you some words which are places or the name of paintings or statues. It also allows you to look at all the words following the one you looked up. I think it is a great dictionary & would highly recommend it. It is also available at a very good price I believe. Take a look! There is an updated 2019 version, but I like what I have very much and hope you will too.

Fairly Good Dictionary App

I have been using this app for a few years, and I finally got sick of the “Review now, Ask Me Later” dialogue box enough to post a review:

It’s a good and reliable dictionary app. I have three total dictionaries on my iPhone, because no single app is enough; although I’ve had this one longest. It has the nice, desirable feature of speaking the word selected. It does a better job than most at providing an accurate pronunciation for most words, but the fault for those words not correctly pronounced is hard to place, as the device itself might often own the blame. I like the feature of inputting first few characters of word during search, which avoids lost time for searching out words that spelling is unknown. I mean, in all but a few cases, I search for spelling purpose more often than definitions. In cases I want definition, it provides good and detailed information, plus derivatives.

I like it, use it often and recommend it. I only give four stars because I have yet to see a dictionary app that is good enough to rate all five...But this one gets top spot.
