IPA: /dɪsˈkɑːrdər/
KK: /dɪsˈkɑrdər/
A person or thing that gets rid of something that is no longer wanted or needed.
The discarder of old clothes donated them to charity.
Discarder → It is formed from "dis-" (meaning apart) and "cardare" (from Latin, meaning to throw away or to get rid of). The suffix "-er" indicates a person who performs an action. Thus, a discarder is a person who throws things away or gets rid of items.
Think of someone who 'throws away' ('cardare') things 'apart' ('dis-') — that's why a discarder is someone who gets rid of items.
