Parentheses

[ImNotThere]

I would be grateful for some advice.

I am helping a friend edit a paper. She explains technical terms using 'i.e.'. Where she has done this in the middle of a sentence, I have enclosed the explanation in parentheses to make the sentence easier to read. When the explanation ends the sentence I have not.

Would you take this approach?

I would say that it depends on the length and complexity of the sentence. I think it would be acceptable to use commas around the section using "i.e." to separate it from the rest of the sentence if it's not too long.

I personally would use brackets (having trouble typing parenthesisisesises ) around all of them or none of them.

I wouldn't use ie at all in a formal document.
It looks neater to put brackets round the explanantion instead of putting ie.
or, you could put little supertext numbers next to each word she's explaining and then have footnotes.
