KK: /sʌbˈhɛdɪŋ/
A title or heading that is placed under a main heading to organize content into sections.
The report included several subheadings to make it easier to read.
Subheading → It is formed from "sub-" (meaning under or below) and "heading" (from Old English "heafdian", meaning to lead or guide). The word "subheading" refers to a title or heading that is placed under a main heading, providing additional guidance or information.
Think of a title that is placed 'under' ('sub-') the main title to provide more details — that's what a subheading does.
