Merriam-Webster’s Dictionary and Thesaurus

Great for elementary students and mommy
I bought this book for my son because he is in 4th grade and needed a dictionary for class. I purchased a simple one for school and this more advanced one for home. He had some difficulty at first, but as he’s practicing, he has become a lot better at finding words and root words. I use this dictionary thesaurus as well, and it works great for me (well, I use it when I get to lazy to log in to the computer). The cover seems to be study as well.

Handy reference
I grew up with a large dictionary at my side during homework time. These days you can search for anything online. However, it is still convenient to have this tool at my side. It’s small print, but easy to use. There’s nothing flashy about it, but it gets the job done.

Perfectly Useless
I bought this to use on my Kindle to look up words I stub my toe on. For this purpose this is certainly not the correct tool.It does not have common foreign words. It has no place names, It does not seem to recognize plurals. Most of the time when I look up a word it comes up with no definition. In fact, I have a new hobby, listing the words this fool thing cannot help you with:Actaeon (Which I admit is a proper noun.)AdzukiAerographerAerologistalchemicalAlembicAnomieAerologistAntioquiaAutarchyBackhanderBecketBindweedBollardBrassicasBrigandageBumptiousnessCanossaCapitaCarcaseCartel, it gives only the economic definitionChayoteChinoiserieCiceronianClientelismCoquettishlyCommunitarianCompanionateCopernicanCoquettishlyCorvidsCyclopeanDiamantairesDirigismeDisjunctDjellabraDottleDouceurDuff (as an adjective)EdamameEnpurpledEntericEpigraphEthnographicEtonianExplicationFarfalleFanegasFendoff (as a noun)FrascatiFuggerei (or any other place name for that matter)GarderobeGravitasGrotesques (as a plural noun)GlacisGlyphosateGozo (It has no place names)GriotHaricotHashemiteHayek”Haymow (n) a mow of or for hay.”HetronormativeHetronomyHippogriffHotspurHyperboreanHypoxiaiatrochemistryIsfahanIterativeKafuffleKasbahKefaloniaKohlLaborantLambicLarboard is defined as “Port.”Lese-majeste (Hyphenated words seem to give this thing fits)Levant (as a verb)ListicleLooplineLoucheMamlukManicheanMenshevik (but Bolshevik is included)MortarmanMullionedMultitundinousnessMusealNeapNeonatologyNobbledNugacitiesOmphalosOrecchietteOstinatoOmphalosOsteriaPercileanPandanus (the plant)PaybookPelengatorPericlean”Peritonitis (Noun) inflammation of the peritoneum”PositoPostulationPoulardPraelectorPreeclampsiaPrelapsarianPsychonerousRejuvenescentReichmarkRepercussiveRictusSabbatarianSaracensSchnitzelShellfireSelf-abnegationSnafuSpartacistsStrammaSubchaserSulphonamideSupererogatoryTempehTephriteThermoelectricTraineeshiptriiodideThrenodicTridentineTrigonTsuris (Yiddish)TridymiteTumefactionUxoricidalVenerabilityVibraphonistVitnineVorticistWakamatsuWhipstaffWracks (the family of plants)WunderkindUnremunerated”Versifier (n) One who versifies.”XebecYellowcakeHow can I return this?

Okay. Limited as a dictionary and as a thesaurus.
The other reviewers appear to address the printed version rather than the Kindle-specific version. I am focusing on the Kindle Application.Strengths — easily used under Kindle platform, terse, usually is clear in distinguishing parts of speech, and it can be used as the default dictionary.Weaknesses1. Definitions are not necessarily any more complete than those from the New Oxford American Dictionary(already built-in on Kindle). Several that I used tonight were less so.2. Definitions for one part of speech are often dependent on another definition listed for another part of speech (a weakness of many dictionaries that is annoying for more complex or unfamiliar words)—-Simple example: the word anger is both a noun and a verb, Thus they define the verb form as “to make angry”.3. Thesaurus component is okay and gives additional ideas for the verb “anger”. However antonyms are very limited if the purpose is to use this as a writing resource. Very few choices.—-For example: antonyms for anger (verb) were delight, gratify and please. But other common options are missing such as calm, sooth, pacify. One would have to keep browsing and unless you set this as the default, you keep ending up in another dictionary when trying to do that.4. Word Origins are sometimes given, mostly abbreviated and with less detail than in Kindle’s Default Dictionary.I have not compared word counts. Sheer mass of definitions is a misleading index of quality.

Dieses Buch sollte man einfach haben um USA -englisch zu lernen

I havent found the kindle version easy to use, and maybe this type of reference book is better as a book format to flick through. Maybe I am showing my generation though…

Thesaurusとは類義語という意味です。私の場合idiomも付いてたらこれ一冊で大助かりでしたが、まあ無かったです。（idiomは別にあります）意味の説明は短く簡素にという感じで最初は慣れませんでしたが段々慣れてきた気がします。発音はアメリカだけです。紙質は再生用紙です。印刷は消しゴムを使うと消えてしまうので注意。問題は英語の小説のペーパーバック型で作られているということです。辞書なので比較的分厚いですし、こんなんで大丈夫なのかなと思いましたが、やっぱり駄目でした。ページの内側を見ようとしたとき「バキッ！」という音が…。案の定接着部分のゴムの部分が折れました。今ではもうしょうがないのでわざと折って開きやすくしました…（セロテープでページが引っこ抜けないようにしてます…）。たった二日目で既に使い古した感じになってしまいました…。最初は落ち込みましたが馴染みましたっ（笑…）。とにかく………な感じです。まあ印刷も荒いです。なんかもったいない気がします、内容はしっかりしているのに。いつまで持つか…。まあ正直「こんなんでよく辞書にしようとしたな」って感じです。（コスト削減のためだろうか）今度は質の改善に期待したいです。（ポケット版ってこんな感じなの？どれも…）
