See the grammar page under .) It is perfectly permissible to make changes to a quoted text, so long as you indicate that you have done so (and if the changes are important, you should actually list them, appropriately in a footnote).
For example, you might wish to quote a text in translation, but be unhappy with some aspects of the published translation you have to hand.
Using quotation marks This style is appropriate for short quotations, particularly those of a few words which are incorporated into the syntax of your own sentences.
Either use single quotation marks on the outside of the quotation, double quotation marks for quotation within quotation, or .
For instance, if you are writing a paper about a colorful public personality, you may want to include a particularly provocative quote made by that person that illustrates their personality.
Using meaningful quotes sparingly can add worth to your writing.
Here is an example: Hume's so-called projectivism is well illustrated by the following excerpt: [T]he mind has a great propensity to spread itself on external objects, and to conjoin with them any internal impressions, which they occasion, and which always make their appearance at the same time that these objects discover themselves to the senses. If you insert words of your own into a quotation (to make the grammar fit your text, or to disambiguate a pronoun, for example), enclose those words in square brackets. When a verse quotation which is incorporated into your text - style (i) above - runs across more than one line of the original, you should mark line divisions with a forward slash (/), and retain the initial capitalisation of the original.
Professors are not stupid; that’s why they have advanced college degrees! Block quotes (of 40 or more words) may be necessary if you are writing about a poem or literature, but they are mostly frowned upon. Use quotes to leave a lasting impression, not to add to a word count! A good quote can also have a strong influence on the reader's experience, drawing the reader into the paper. The reader will be left with the impact of that quote.
They know the tricks of the trade, and adding long quotes to a paper to meet the word count is one of the oldest tricks. The general rule is that a paper should include less than 20 percent quoted material. If you believe that you need to use quotes, choose ones that are pronounced and will add value to your paper.
If the quote is an effective one, it can add a powerful message or feeling to the document. Ending a paper with a quote can have the same effect on the reader.
