Quotation marks are often used with technical terms, terms used in an unusual way, or other expressions that vary from standard usage. Examples: It's an oil-extraction method known as “fracking.” He did some “experimenting” in his college days. I had a visit from my “friend” the tax man.

In British English, punctuation marks such as commas, periods, question marks, and exclamation marks are typically placed inside the closing quotation mark, unless they belong to the surrounding sentence rather than the quoted material. Example: Correct: She asked, ‘What time is the meeting?’ Incorrect: She asked, ‘What time is the meeting’?
