What are quotes and why are they used?

The first thing to understand is why it should be quoted in the first place. Your own texts should reflect your thoughts, but also deal critically with the opinions of other authors. Quotations are used to check, confirm or refute statements. It is often paraphrased, which means that no literal quotations are used. You formulate the statement in your own words and identify it with the source from which the statement comes. As soon as text passages are taken over word for word, they must be placed in double quotation marks and marked as a quotation. The text passage or the sentences that you adopt may not be changed in terms of wording, spelling or punctuation. If you add missing parts of sentences or words or omit superfluous parts, these passages are put in square brackets.
