A more thorough explanation:

A slanderer is a person who spreads false and damaging statements about someone else, with the intention of harming their reputation.

• John was accused of being a thief by a slanderer who had no evidence to support their claim.
• Mary's reputation was ruined by a slanderer who spread rumors about her personal life.
• The politician was the victim of a slanderer who spread lies about their policies and character.

These examples illustrate how a slanderer can cause harm to someone's reputation by spreading false information. Slander is a serious offense and can have long-lasting consequences for the victim.
