Using adjective clauses to modify personal pronouns

[Sam165]

Hello teachers

My question is that in a grammar book I've read that almost never adjective clauses are used to modify personal pronouns, yet there was an exception
It was said that it's very formal and uncommon
The example of that : It is I WHO am responsible.

But there was no other explanations so I'm very confused now, is there a specific formula for using adjective clauses to modify personal pronouns? Or any specific explanation?
I googled it but I couldn't find the answer for it so I look up to your answers

At your current level, you will do well to follow Azar's advice: don't use adjective clauses to modify personal pronouns.

What more do you need to know?

Thank you. ♡ (I don't know how you created that symbol. You need a full stop/period.)

The simple answer is that you should not use adjective clauses to modify person pronouns. It's formal and ​uncommon.

For my writings it's good to know a few formal things it would really be a great help for me to get my desired scores
I know that my english is not that formal and perfect to use such things, but I gotta start somewhere to reach that level
However I also may not use it, but it's good to know the exact explanation
when something is unclear to me even if I don't use it, it would make me confused that's why I try to at least know the basics of this formal and uncommon thing

The only combination I can think of is "He who ..."

He who pays the piper calls the tune.

Yes they are important things to know, I haven't still studied punctuations so I have quite a few mistakes in this field. Thank you for your help.

We can find other examples:

He who dares wins
We who are about to die salute thee.
It's you who are to blame.

It's not a good idea to try the same.

Thank you so much your answers were helpful

For my writing it's good to know a few formal things. It would really be a great help for me to get my desired scores.

Formal does not mean unnatural. The phrasing you're asking about is not natural. Formal writing should be natural.

To improve your scores, master the basics. Don't sweat the small stuff.

I know that my English is not [STRIKE]that[/STRIKE] formal and perfect enough to use such things, but I have to start somewhere to reach that level.

The place to start is with the basics. THEN go on to difficult, trivial questions like the one you posted. Go back to the basics, and ask the question again here in two or three years.

However, I also may not use it. But it's good to know the exact explanation.

The advice they've given you above is good.

When something is unclear to me, even if I don't use it, it confuses me. That's why I try to at least know the basics of this formal and uncommon thing.

1. "Who am I" "who I am" are common and natural. I have never in my life heard "I who am." Don't use it!

2. An easy way to improve your scores is to work on your punctuation and capitalization. (See the corrections above.)

3. Another is to avoid words like gotta, wanna, dunno, coulda, sorta, and lol.

Thank you so much! Your answers were helpful.

 

[emsr2d2]

so I make quite a few mistakes at it

I would use "with it", not "at it".

The example of that : It is I WHO am responsible.

It's you who are to blame.

These are cleft sentences, if I'm not mistaken.

 

[PaulMatthews]

These are cleft sentences, if I'm not mistaken.

It is I who am responsible
It is you who are to blame.

You are right: these are it-cleft relatives.

Because they are clefts, the relative clauses here do not modify their antecedent ("I/you"), i.e. they do not combine with it to form a constituent.
