Thorough breakdown accompanied by example sentences

<div class='writeup-body'>さえ is an adverbial particle in Japanese that is used to place emphasis on something existing in certain state. It is often translated as 'even'. さえ has three primary meanings, which are as follows: Analogical Reasoning: 類推（るいすい） - Analogy, (A) is an outstanding example of something. Limit: 限定（げんてい） - Limit, (A) is all that is needed for something. Addition: 添加（てんか） - (A) compounds something that is pre-existing. さえ is regularly paired with other particles and is often followed by verbs in negative form, with the overall meaning usually being determined by what part (B) of the sentence is conveying. Let's look at a few examples.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>上級者（じょうきゅうしゃ）の彼（かれ）でさえ出来（でき）ないのに、あなたが出来（でき）るわけがないでしょう。</div><div class='writeup-example--english'>Even someone in the advanced class level can't do it, there is no way you can do it.</div></li><li class='writeup-example'><div class='writeup-example--japanese'>彼女（かのじょ）は親（おや）にさえ知（し）らせずに彼氏（かれし）と結婚（けっこん）をした。</div><div class='writeup-example--english'>She got married to her boyfriend, even without telling her parents.</div></li><li class='writeup-example'><div class='writeup-example--japanese'> 彼（かれ）はストレスのせいで、晩飯（ばんめし）を食（た）べることさえ出来（でき）なくなった。</div><div class='writeup-example--english'>Due to him being stressed, he couldn't even eat.</div></li><li class='writeup-example'><div class='writeup-example--japanese'>タナカ君（くん）は酷（ひど）くない？彼女（かのじょ）を傷（きず）つけたのに、謝（あやま）りさえしなかったらしいよ。</div><div class='writeup-example--english'>Don't you think Tanaka-kun is a jerk?

This relationship can be seen here: (A) は - (A) is completely expected, there is nothing unusual. (A) も - (A) will be included as part of what is expected, but can be unusual. (A) でも - (A) may or may not be included as part of what is expected, and can be unusual. (A) さえ - (A) is separated completely from what is expected, and is unusual. Due to this unexpected and unusual situation that さえ always presents, it is regularly translated as 'let alone (A)', or 'not to mention (A)'.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>このレベルはプロでさえ難（むずか）しいというのに、よくできたね。</div><div class='writeup-example--english'>I am impressed you were able to do this, let alone that it is difficult even for professionals.</div></li><li class='writeup-example'><div class='writeup-example--japanese'>トムがこんなに漢字（かんじ）を知（し）っているのは凄（すご）いと思（おも）うよ。日本人（にほんじん）でさえ漢字（かんじ）は難（むずか）しいのに。</div><div class='writeup-example--english'>Tom, I think it is impressive that you know this many kanji.
