A process or state in which something is reduced in quality, value, or condition.
The degradation of the environment is a serious issue that needs to be addressed.
Degradation → It is formed from "de-" (meaning down or away) and "gradus" (meaning step or degree) and the suffix "-ation" (indicating a process or action). The word describes the process of stepping down or a decline in quality or status.
Think of 'stepping down' ('gradus') and 'away' ('de-') to remember that degradation means a decline in quality or status.
