When writing a research paper and quoting someone, how do you add info within the qoute?

I am writing a research paper and I want to make a comment about a term within a quote that I am using. Can I add information in parenthesis or brackets and make it understood that it is not apart of the original qoute?

When writing a research paper and quoting someone, how do you add info within the qoute?
There are two common ways:


1. At the bottom of the page, define the term.


2. If it's a key word, you can define it after the abstract and before the introduction part.





But it really depends on which research field you're at.You should look at a research journal before you write the paper.
Reply:Adding parenthetical information could be distracting if it's long. Try footnotes or endnotes.
Reply:If your quote is included within the reference,it means it's a part of the original. Better you explain later after the main reference.Alternatively, u can explain any term in 'introduction' section before the contents of your paper.
Reply:Put a bracket in. For example "if this was a quote [and this was additional info] then you could continue your quote on from there."
