Onychomancy

Onychomancy or onymancy (from Greek onychos, 'fingernail', and manteia, 'fortune-telling') is an ancient form of divination using fingernails as a "crystal ball" or "scrying mirror" and is considered a subdivision of palmistry (also called chiromancy).

[1][2] As with palmistry, the contradictions between different interpretations and the lack of evidence for the predictions have led onychomancy to be viewed as a pseudoscience by academics.

[5] Practitioners of onychomancy relate patterns observed on the fingernails with chakras, reflexology points, astrological interpretations of planets and Tarot.

It is also believed that the longer the nails are the larger the crown and 3rd eye chakra regions are and hence the more intuitive and receptive the person.

[5] A subdivision of onychomancy, called Kikimancy, relates the shape of the nails to the classical elements (earth, air, fire and water), Yin and yang and personality types.
