# Can I use the word each twice in my sentence

I have a mixture of two subjects. I can call each of them as a mixture component. I would like to store each mixture component in its own matrix.

From my old question here, I may write my sentence as follows:

The numbers, letters, and mixture components are each stored in a separate matrix.

This may make the reader think that I stored my mixture components in one matrix, which is incorrect. Therefore, I would like to clarify my sentence even further.

The numbers, letters, and (each) mixture component are each stored in a separate matrix.

I just wonder if this correct? or I must not use `each` twice in my sentence.

The best way might be:

The numbers, letters, and every mixture component are stored in separate matrices.

"Every" makes sure that the mixture components are separated, and "matrices" is the plural of matrix.

As I understand correctly, you have the following:

Matrix A: the numbers.
Matrix B: the letters.
Matrix C: mixture component #1.
Matrix D: mixture component #2.

If this is correct, then it might make more sense to restructure the sentence.

It's tricky to express completely clearly, but I suggest something like this:

Each matrix exclusively stores one of: the numbers, the letters, or an individual mixture component.

If I'm mistaken, it could be the following that you have:

Matrix A: mixture component #1, with some numbers and letters.
Matrix B: mixture component #2, with some numbers and letters.

If so, I suggest the following:

Each individual mixture component is stored in its own matrix, along with its numbers and letters.
