upsetting. 混乱中　?(ﾟ_｡)?(｡_ﾟ)?

Have you ever been confused when you are learning a language?
言葉を勉強していて混乱したことはありませんか？

forFor instance, between similar words, like "complain" and "compliment".
例えば、似たような単語「complain」と「compliment」みたいな。

If you saidwere to say to me, "you have a beautiful hair". I should [reply and] say, "thanks for your compliment.".
もしあなたが私に「綺麗な髪だね」って言ったなら、私は「褒めてくれてありがとう」というわなきゃね。

But that case isit would be wrong that if I said "thanks for your complaint".
でも、「あなたの不平に感謝するわ」は間違いだもんね。

I have a lot of like that words. There are a lot of words like that to me.
私はそういう単語がたくさんあるの。

another forHere's another instance, "explain","experience","experiment".
他にも、"explain","experience","experiment"とか。

That meanings isare too different, that's why if I have wrong how to usewere to use the wrong one, I may give you impoliteend up being impolite to you.
意味はあまりにも違うからもし私が間違った使い方をしたら、失礼になるかもしれないよね。

Did you haveHave you had like that experiences like that?
そんな経験ありませんか？

Good job!

I added "were to" in "If you were to say to me", and "If I were to use the wrong one".  Strictly speaking, "were to" is not necessarly needed, however, I think it makes it sound a bit better, because it emphasizes the situation is hypothetical.

"like that" should follow the noun, such as "words like that", and "experiences like that".

The correct verb that goes with impolite/polite is "be", instead of "give".
