means The title or label placed at the top of a section, text, or list to indicate what it's about.

from From 'head,' the Old English 'heafod,' meaning the topmost part of the body — extended metaphorically since medieval times to mean the top or front of anything, from the head of a table to the head of a document. 'Heading' as the forward-facing top of written material follows naturally: the part that leads, the way your actual head leads your body.
