What does punctuation mean?
Punctuation is the system of marks and signs used in writing to make meaning clearer and guide the reader through spoken language. Its familiar marks include the period, comma, semicolon, colon, question mark, exclamation mark, quotation marks, apostrophe, hyphen, and parentheses. Punctuation can show where sentences end, separate clauses, mark questions or exclamations, indicate possession, and distinguish quoted material from a writer's own words. It is therefore not merely decorative: it helps organize grammar and can change a sentence’s interpretation. Rules and conventions differ between languages and can vary between British and American styles, but the central purpose remains the same—to make written communication easier to follow.

Where does punctuation come from?
The word entered English from Medieval Latin and ultimately derives from Latin punctum, meaning a point or prick, with the related verb pungere meaning to prick or puncture. The Latin noun developed through the sense of a point made in writing and, by extension, the marks and divisions associated with written speech. Modern English inherited both the general noun and its more specific sense of written marks through the development of punctuation from the practice of inserting points into text. Its relatives include punctual, punctilious, compunction, and poignant, all associated with the same Latin family of pointing and pricking meanings.
