IPA: /ˈbækˌboʊn/
KK: /ˈbækˌboʊn/
The main support or structure that holds something up, often used to describe a key element that provides strength or stability.
The backbone of the organization is its dedicated staff who work tirelessly to achieve its goals.
Backbone → The word is formed from "back" (from Old English "bæce", meaning the rear part of the body) and "bone" (from Old English "ban", meaning the hard, calcified tissue that makes up the skeleton). The term "backbone" refers to the series of vertebrae that form the spine, which is located at the back of the body and provides structural support.
Think of the 'back' as the rear part of the body and 'bone' as the hard structure that supports it. This helps you remember that a backbone is the supportive structure at the back.
