Is it acceptable to use an exact words as long they are put in quotation marks and the author is credited?

It depends on the context and purpose of using the exact words. In general, it is considered plagiarism if you use an exact phrase or sentence from someone else's work without giving them credit. However, there are some exceptions to this rule.

When you can use exact words without credit

* When the words are common knowledge or facts. For example, you do not need to give credit if you use the phrase "the sky is blue" or the fact that "the Earth revolves around the Sun."

* When you are using a quote from a source that is clearly labeled. For example, if you are writing an article about a speech given by a politician, you can quote from the speech without giving credit as long as you clearly label the quote.

* When you are using words in a non-profit educational setting. For example, if you are teaching a class about a particular book, you can use exact words from the book without giving credit as long as you are doing so in a non-profit educational setting.

When you must give credit

In all other cases, you must give credit to the original author when using exact words from their work. This can be done by including a citation in the text of your work, and a reference list at the end of your work.

How to give credit

The format for giving credit to the original author will vary depending on the style guide you are using. Some common style guides include the Modern Language Association (MLA) style guide, the American Psychological Association (APA) style guide, and the Chicago Manual of Style.
