What is this mean " I am quite concerning too in that sense."

Hello, Carter—and welcome to English Forums.

Carter LeeI am quite concerning too in that sense

That sentence is wrong. One of these is meant instead:

I am quite concerned too in that sense = I am worried
It is quite concerning too in that sense = It is worrisome

Thanks sir,

I would understand you answer.
But i have.a query about too usage.
Actually it was hardly understood. Why there is 'too'?
What having a meaning in the sentence whether 'too' use it or not.
In more detail, actually i am confused between quite and too.
How can use both them in one sentence.?

Carter LeeWhy there is 'too'?

We cannot judge without more context. 'Too' = also. Too' does not mean 'quite, very' in that sentence. The speaker and also someone else are very (quite) concerned, or the speaker is very (quite) concerned about one thing and also about another thing.
