10000 words

Lately, I have learned 40-60 English words everyday using an online learning site of my university.

And yesterday, the number of words that I learned finally reached 10000.

There remains only other 2000 words.

However, as the number increases, the difficulty also increases, so now the learning takes a lot of time and is a little painful to me.

Today, I try to make a sentence using some words that I learned a little while ago so as not to forget them.

"The dingy and abominable bureaucrat spat out hackneyed epithets in a circumspect way."

10000単語

私は最近、大学のオンライン学習サイトで毎日40-60の英単語の勉強をしています。

そして昨日、勉強した単語数がようやく10000に達しました。

残り2000単語で、全ての学習が終わります（もちろん復習は続きます）。

しかし、勉強を進めるにつれて単語の難しさが上がってくるため、時間がかかって辛いです。

今日は学んだ単語を忘れないようにするため、例文を作る練習をしてみます。

その薄汚くて忌まわしい官僚は、慎重に使い古された悪口を吐き捨てた。
（The dingy and abominable bureaucrat spat out hackneyed epithets in a circumspect way.）

• Lately, I have learned 40-60 English words everyday using an online learning site of my university.
• Lately, I have been learning 40-60 English words every day using an online learning site of my university.

  "have been learning" more natural. It says that you are continually learning.
  
  "everyday" and "every day" has a slightly different meaning. "Every day" is correct for what you want to say.
  "Everyday" is an adjective, eg. ' It's my everyday routine.'

• And yesterday, the number of words that I learned finally reached 10000.
• Yesterday, the number of words that I learned finally reached 10000.

  My school teachers would complain if I start a sentence with "and" (but I think it's not technically incorrect.)

• There remains only other 2000 words.
• There are only another 2000 words remaining.

  "another" is optional.
  
  Another way to write is "There are only 2000 more words remaining."

• However, as the number increases, the difficulty also increases, so now the learning takes a lot of time and is a little painful to me.
• This sentence is perfect! No correction needed!

• Today, I try to make a sentence using some words that I learned a little while ago so as not to forget them.

• "The dingy and abominable bureaucrat spat out hackneyed epithets in a circumspect way."
• "The dingy and abominable bureaucrat spat out hackneyed epithets in a circumspect way."

  I had to check the meaning of those words! haha

Congratulations on 10,000 words!
