A person or thing that causes someone to lose confidence or hope.
The constant criticism from his boss was a real demoralizer for the team.
Demoralizer → It is formed from "de-" (meaning down or away) and "moral" (from Latin "moralis", meaning relating to manners or ethics) and "-izer" (a suffix indicating a person or thing that performs an action). The word "demoralizer" refers to someone or something that brings down or undermines moral standards or confidence.
Think of someone who takes away your confidence or ethical standards — 'de-' means down, 'moral' relates to ethics, and '-izer' indicates a person who does something.
