A quote or citation is a literal statement made by someone, quoted by someone else. Quoting differs from paraphrasing in that the latter form reflects ideas of others in their own words (the idea is maintained, but the form is different from quoting).
When citing phrases, your own text should be written in such a way that the quote is seamlessly integrated. If that is not entirely successful without, for example, moving a verb from the quotation or putting it in a different tense, then this operation should be marked by putting the word between square brackets. If something from the quoted part is not quoted, the omission must be marked with an ellipsis: three dots between round brackets.
