It seems like the phrase "in the lips" in your question might be a typo or a misinterpretation. However, if you are asking why an author may use quotation marks (") to make words from a quote, the most likely reasons are:
1. To distinguish the quoted material from the author's own words or writing. This helps the reader understand that the enclosed text is directly taken from another source.
2. To indicate when someone else is speaking or being referenced. Quotation marks are commonly used to represent dialogue or direct speech, allowing readers to identify who is speaking in a conversation or narrative.
3. To emphasize specific words or phrases. Quotation marks can be used to draw attention to particular terms or ideas in a quote, highlighting their significance or providing readers with a focus point.
Ultimately, the use of quotation marks serves to provide clarity, attribution, and emphasis within a text, ensuring that the reader can distinguish between different voices and understand the source of the information.
