IPA: /dɪˈsɛnt/
KK: /dɪˈsɛnt/
A movement downwards, either physically or in terms of status or level.
The hikers carefully made their descent down the steep mountain.
Descent is formed from "de-" (meaning down from) and "scendere" (meaning to climb or to go). The word describes the act of going down or descending from a higher place.
Think of going 'down from' ('de-') a higher place, which helps you remember that 'descent' means to go down.
