Which term describes a single line carried over to the top of a new page?

The term that describes a single line carried over to the top of a new page is known as a "widow." In typesetting and layout design, a widow refers specifically to the last line of a paragraph that appears by itself at the top of a new page or column, thereby creating a visual imbalance. The term highlights the isolation of that single line and emphasizes the need for thoughtful formatting to maintain the cohesion of the text. Effective technical writing strives to avoid such situations, as they can disrupt the reader's flow and comprehension. This concept is part of broader principles in technical writing aimed at improving readability and presentation of information.
