The standard 78 card deck used today can be split into two sections, these being the Major and Minor Arcana.
The 22 cards of the Major Arcana are often considered the most important cards of the deck and usually represent significant issues in the life of the Querent (person having their tarot read). They bring up the key principles core to human life and consist of archetypes- recognised and highly symbolic figures across mythology and religions.
The 56 Minor Arcana cards are considered to be the ancestors of contemporary playing cards, and just as so they are divided into four suits with ten pip cards and four court cards. (Wands corresponds to clubs, cups to hearts, swords to spades and coins to diamonds>)
The suit of cups is generally associated with emotions corresponding to the astrological element of water. The suit of swords which corresponds to the element of air is generally associated with intellectual activity . The suit of wands is associated with career and corresponds with the element of fire. And lastly the suit of coins/ pentacles corresponding with the earth element is associate with financial and material aspects.
