The word “internecine” is derived from the Latin word “internecinus,” which means “murderous, deadly.” The term is often used to describe conflicts that occur within a group or organization, such as a political party, family, or business. These conflicts can be extremely destructive and can result in a great deal of harm, damage, and loss of life or property.

The adjective “internecine” can also be used to describe a situation where two or more parties are engaged in a bitter and deadly struggle against each other. In such cases, there may be a sense of hostility, hatred, or even enmity between the parties involved.

The term “internecine” is often used in a negative context to describe situations where conflict and strife are causing serious harm to individuals or to the larger group or society. It is also used to describe situations where there is a sense of futility or hopelessness in resolving the conflict, as the parties involved are unwilling to compromise or negotiate. In such cases, the conflict may continue until one party emerges victorious, or until both parties are so weakened that they are unable to continue the struggle.

Prefixes and suffixes can be added to the word “internecine” to create new words with related meanings. For example, the prefix “in-” can be added to form “internecine,” which means “causing internal destruction.” The suffix “-ary” can be added to create the word “internecinary,” which refers to a person or group that is responsible for causing harm or destruction to others.
