Animus (noun, pronounced AN-ih-muss) refers to a deep-seated feeling of ill will, bitter anger, or active hostility toward someone or something. It implies a strong, often prejudiced, dislike or animosity. In legal contexts, it signifies a specific intention or mental purpose, while in Jungian psychology, it represents the masculine inner personality of a woman.

Key Aspects of Animus:
    • Hostility: It is a formal term for intense dislike, hatred, or bad blood, often rooted in prejudice.
    • Legal/Formal Usage: It can describe the “intent” or motivating spirit behind an action (e.g., animus furandi — intention to steal).
    • Examples:
       “The politician’s
      animus
       toward her rival was clear” or “He harbors no personal
      animus
      .”
  • Related Words: Synonyms include animosity, enmity, ill will, antagonism, and malice.

Animus has long referred to the rational or animating components of a person’s psyche (it derives from Latin animus, which can mean “spirit,” “mind,” “courage,” or “anger”). Since a key animating component of personality can be temper, the word came to mean animosity, especially ill will that is driven by strong prejudice. The term is also used in the analytic psychology of C. G. Jung in reference to an inner masculine part of the female personality. The English animus is closely related to words such as animositymagnanimous, and unanimous, but it is not as closely related to other similar-looking terms such as animal and animate. Those latter terms derive from the Latin anima, a distinct term that means “soul” or “breath” and that suggests someone’s physical vitality or life force—the breath of life.

animus meaning in law

Animus in law is a Latin term meaning “mind,” “intention,” or “disposition,” referring to a person’s underlying purpose or mental state behind an action. It is critical for establishing legal intent, such as animus furandi (intent to steal) or determining if actions were motivated by discriminatory “class-based animus”.

Simple Definition of animus

Animus primarily refers to ill will or animosity, particularly a prejudicial disposition toward a discernible group, known as “class-based animus.” More broadly, it signifies intention or purpose, and is frequently used in Latin legal phrases (e.g., *animus furandi*) to specify a particular state of mind or goal.

Definition of animus

In legal terms, animus is a Latin word referring to a person’s state of mind, specifically their intention, motive, or underlying disposition. It can be understood in two primary ways:

  • Ill Will or Animosity: This refers to a strong feeling of hostility, prejudice, or antagonism towards another person or, more commonly in legal contexts, towards a specific group of people. When directed at a constitutionally protected group (e.g., based on race, religion, gender, or national origin), it is often called “class-based animus” and can be a critical element in civil rights cases.
    • Example 1 (Class-based animus): A landlord consistently rejects rental applications from families with young children, despite having available units and the families meeting all financial criteria. During a fair housing investigation, emails are discovered where the landlord expressed a strong dislike for “noisy kids” and a belief that families with children cause more damage to property.Explanation: The landlord’s repeated rejections and the discovered emails demonstrate a clear class-based animus against families with young children, which could be a violation of fair housing laws prohibiting discrimination based on familial status.
    • Example 2 (General ill will): After a contentious business partnership dissolved, one former partner began spreading false and damaging rumors about the other to mutual clients and industry contacts.Explanation: The deliberate act of spreading false rumors, especially after a bitter separation, indicates a strong animus or ill will from one partner towards the other, potentially leading to a defamation lawsuit.
  • Intention or Purpose: This refers to the specific mental state or purpose behind an action. In this sense, animus is frequently combined with other Latin words to describe a precise legal intention.
    • Example 1 (Animus furandi – intention to steal): A shopper picks up a valuable piece of jewelry from a display, quickly puts it into their pocket, and walks towards the exit without any intention of paying for it.Explanation: The act of concealing the jewelry and attempting to leave the store without payment clearly demonstrates animus furandi, which is the specific intention to steal, a necessary element for a theft charge.
    • Example 2 (Animus manendi – intention to remain permanently): A foreign national applies for citizenship, having lived in the country for many years, established a successful business, bought a home, and integrated into the local community, showing no signs of planning to leave.Explanation: The individual’s long-term actions and commitment to their life in the country demonstrate animus manendi, indicating a clear intention to reside there permanently, which is a key factor in determining legal domicile for citizenship purposes.
    • Example 3 (Animus testandi – testamentary intention): An individual, while of sound mind, drafts a handwritten note stating, “This is my last will. I leave everything to my niece, Sarah,” signs it, and has two friends witness their signature, even if the document isn’t prepared by a lawyer.Explanation: Despite any informalities, the clear language, signature, and witnessing indicate animus testandi, meaning the individual intended this document to serve as their valid last will and testament, expressing their wishes for asset distribution after death.
Key aspects of animus in legal contexts include:
  • State of Mind: It represents the subjective intention (the “mind with which a thing is done”) rather than just the physical act itself.
  • Specific Legal Terms: It is used to define specific legal intent, such as animus possidendi (intention to possess), animus revocandi (intention to revoke a will), or animus donandi (intention to give).
  • Discrimination/Hostility: In civil rights law, “class-based animus” refers to malicious, hostile, or prejudicial intent toward a specific group.
  • Criminal Law: Animus helps determine liability, often distinguishing between accidents and deliberate actions (e.g., animus nocendi or the intent to harm).
It is distinguished from mens rea (the guilty mind required for a crime), with animus often focusing more specifically on the intent behind a specific action

Distinction from “Motive”
While often used interchangeably in casual conversation, legal practitioners distinguish “animus” from “motive.” Animus (intent) refers to the will to do the act itself, whereas motive refers to the reason why the person wanted to do it. For example, in an employment discrimination case, a court may look for retaliatory animus
