Can someone please check for any spelling/gammar mistakes? Dear Ms. {name},

I would like to particularly thank you for all that you have taught us through the whole semester, which is quite significant. I am immensely grateful for such energetic and fulfilling lessons you essentially teach us about the powerful vikings roaming all over earth, The gruesome kind of Black Plague and so much more. It contains my sorrow seeing you leave {school name} after all the things you taught students and especially Grade {number}

Explanation:

Dear Ms. {name},

I would like to particularly (the word specifically would make more sense here) thank you for all that you have taught us through (throughout would be a better word than through, but either works) the whole semester, which is (you should write all of which was quite significant instead of which is...), quite significant. I am immensely grateful for such (replace such with for all of the) energetic and fulfilling lessons you essentially (essentially doesn't make sense here) teach (taught, not teach since you're talking about the past) us about the powerful vikings roaming all over earth, The (the shouldn't be capitalized) gruesome kind of (no need to put the words kind of) Black Plague and so much more. It contains my sorrow seeing you leave {school name} after all the things you taught students and especially Grade (don't capitalize grade) {number}.

This is a very sweet message btw!

Hi! ＼(^。^ )

I founded a mistake in your letter.

First, I founded is the part where you thank to someone,

"I would like to particularly, thank you for all"

My problem is, you forgot to put a comma.

Second, You should put a Period (.) to the end of the letter.

That's all! I hope i can help.
