Step 1: Read the situation.
Someone is being forced to marry against their own wish. We must name which kind of domestic violence this is.
Step 2: Know the types of abuse.
Domestic violence is wider than just hitting. It can be physical, economic, mental, and emotional. Each type harms a person in a different way.
Step 3: Understand emotional abuse.
Emotional abuse means controlling, threatening, or pressuring a person in ways that hurt their feelings, dignity, and freedom of choice, even when no physical injury is caused.
Step 4: Test physical and economic abuse.
Forcing a marriage does not mean beating the person, so it is not mainly physical abuse. It also does not involve money matters, so it is not economic abuse.
Step 5: Match the act to the type.
Forcing marriage attacks a person's free will and emotional well being. That fits emotional abuse most closely.
Step 6: Confirm the answer.
So forcing someone to marry against their will is a form of emotional abuse.
