1
person who commits murder
A person who illegally and on purpose kills another person.
Usage pattern:
[someone] is a [adjective] murderer
Common mistake:
Learners sometimes confuse "murder" and "murderer". "Murder" is the act (e.g. "The murder happened at night"), while "murderer" is the person (e.g. "They arrested the murderer"). Another confusion is with "killer", which can be used more broadly for any person or thing that kills (e.g. "shark attack killer", "silent killer" for a disease), while "murderer" almost always refers to a person who commits the crime of murder.
Synonyms
killer (Broader; can mean any person or thing that kills, not always illegal or intentional.)
|
homicide offender (More technical and legal; mainly used in formal or legal contexts.)
Antonyms
victim (Refers to the person who is harmed or killed, the opposite role of the murderer.)

2
person or thing that ruins something
A very strong way to talk about a person or thing that badly hurts or ruins something, not by really killing.
Usage pattern:
a murderer of [something abstract]
Common mistake:
Learners may think this figurative use is neutral, but it is very strong and emotional. It should only be used when you want to sound dramatic or humorous, not in calm, objective descriptions.
Synonyms
destroyer (Very close in meaning but less emotionally shocking; does not carry the strong killing image of "murderer".)
Antonyms
protector (Someone who keeps something safe, the opposite of a person who is said to "murder" it.)
