Equivocal words E. have more than one commonly accepted definition.
Equivocal means ambiguous - that means that a word can mean several different things at the same time. What that particular word is going to mean in a sentence or a text is going to depend on the context. Without the context, it will be difficult to decide what the actual meaning of that particular word is because it could mean so many things.
Assuming you meant explanatory text and not exclamation text, the answer would be brackets. For example, say your quotation is "She wrote the book." If you are quoting this directly in a paper, you want your audience to know who "she" is. So, you use brackets, and write the following: "[J.K. Rowling] wrote the book." Hope this helps.
