Widows and orphans

In typography, an isolated line of text starting/ending a page

In typesetting, widows and orphans are single lines of text from a paragraph that dangle at either the beginning or end of a block of text, or form a very short final line at the end of a paragraph. When split across pages, they occur at either the head or foot of a page, unaccompanied by additional lines from the same paragraph. The pairing of the two terms with their definitions has no consistent standard across the industry; some sources use the opposite meanings as others. Additionally, a runt, which varying sources also call a widow or orphan, is a very short ending to a paragraph occupying only a small portion of its own line.
