I have a sentence:
Before the Greeks, the ancient Egyptians used it (Golden Section - remark is ours) in the construction of their great pyramids.
In that sentence the words "Golden Section" was written by me - not by the author of the sentence.
In which words (remark is ours; note ours or something else?) do I say (designate) that the notes inside a quote are mine?
What are the most common words (phrases) for such cases (except "italics mine," "my italics," and such; I am not interested in that)?
