Relationship Lines
Short horizontal lines at the edge of the palm below the little finger are often called relationship, union, or affection lines in palmistry.
How palmists traditionally read it
Popular books sometimes call them marriage lines, but they do not reliably count marriages, children, divorces, or relationship dates. Schools disagree heavily about their meaning.
Use it as reflection, not fate
Use them as prompts to think about commitment, partnership expectations, and the difference between intimacy and social convention.
Keep the claim modest
Hand features vary naturally with anatomy, age, occupation, movement, injury, and skin condition. Palmistry does not scientifically establish personality, health, lifespan, fertility, intelligence, or future events.
