Traditional palmistry says marriage or union lines can suggest important relationships, emotional timing, or patterns of attachment. These lines sit on the outer edge of the palm below the little finger, near the Mount of Mercury.
That is a cultural reading system, not a verified forecasting instrument. A palmist may combine union lines with the heart line, fate line, Mount of Venus, and overall hand shape, but the result is interpretation rather than measurement.
The most careful way to use this tradition is as reflective language: a prompt for thinking about intimacy, commitment, temperament, and expectations, rather than a schedule of future events.
