Thorough, Exhaustive, Perfect

I wanted a good, easy-to-use resource for synonyms, because I am a writer and often find myself on a quest for that elusive Right Word. I wanted a meal, and got a banquet with this app. Just type in kind-of the word you want, and you will get a rich, exhaustive list of every possible synonym. Enlightening and entertaining. I learn a good handful of new words each time I use it.
I use this app so often that I decided it was time to give it the 5-star review it deserves!!

Abundant search results

If you are interested in a thesaurus that offers numerous search results—far more per entry than is the norm—then this will be a great resource to you.

Bear in mind that for each entry, many of the proposed synonyms' meanings will be only tenuously similar to that of the word on which you've performed your search.

Also, the results are not grouped separately for each of the searched word's distinct meanings; e.g., synonyms for the word 'steel' will not be separately grouped for the verb form and for each of the various forms of the noun. instead they will all be grouped together in one long list, ordered alphabetically.

i hope that helps. (i use it every day.)
