The definition of rape may differ from one jurisdiction or country to another. In most jurisdictions, rape is defined as the forceful act of engaging in sexual intercourse with someone above a certain age against the person’s will or wishes.
This person in question must be old enough to consent to sexual intercourse which makes it wrong to engage in sexual intercourse with such a person without his or her consent.
In some countries, the age limit is 16, 18, 20, etc. This means that the victim should, at the time of the rape, be of the said age or more. If the victim is found to be below the said age, then there is no rape but defilement.
In most countries, rape is a criminal offence which is punishable under the laws of the country to a term of imprisonment or fine or both.
