Definition of punctuation mark in English:
A mark, such as a full stop, comma, or question mark, used in writing to separate sentences and their elements and to clarify meaning.
- Normally, a comma or other punctuation mark separates the ending or resumption of direct speech from its interruption.
- The test words were not included in the first and the last sentence of the text, they were never at the beginning or the end of a sentence, and they were never adjacent to a punctuation mark.
- That is, unless they changed their style, dropped all those references to dead white males and the occasional punctuation mark.
