Scroll down to Words as words.

Either way is correct; it depends on the specific style guide or personal preference you are following.

In general, using quotation marks around a word or phrase can indicate that you are referring to the word itself, rather than using it in context. So, if you are discussing the etymology or meaning of the word "peace", using quotation marks could highlight that you are referring specifically to the word itself.

However, if you are using the word "peace" within a sentence to convey its meaning or discuss it without focusing on the word itself, you may omit the quotation marks. In this case, the word "peace" is being used in its standard context.

Ultimately, it's important to be consistent within your writing or follow the specific style guide that you are using, such as APA, MLA, or Chicago style, to determine whether or not to use quotation marks around the word "peace".
