The Suit of Cups
This suit relates to the Element of Water, and deals primarily with emotions and relationships. (Please note that there are many types of relationships, not just love relationships such as boyfriend/girlfriend or marriages. You also have relationships with parents, children and other relatives, co-workers, bosses, etc.)

Ace
(This card usually depicts a chalice hovering above a body of water. The chalice is usually overflowing.)
The Ace of Cups signals an outpouring of emotion. There is the potential for a new relationship, often with a person as yet unknown to the Querent.
Reversed, this card can indicate a blockage of emotion, an unwillingness to let go and enjoy a relationship.

Two
(This card usually depicts two young lovers, each holding a cup. Often, there is a cherub smiling down at them.)
The Two of Cups signifies the beginning of a relationship, or the healing of one that has undergone difficulties. In either case, there is a sense of union and partnership.
Reversed, this card can indicate difficulties caused by the partners being on different wavelengths, or one putting more into a relationship than the other is.

Three
(This card usually depicts three figures clustered together, each with a cup.)
The Three of Cups indicates a relationship moving onto a new, deeper level. This could indicate "going steady," an engagement, etc, and sometimes it will indicate pregnancy, especially if the Querent is involved in a steady relationship and they want children.
Reversed, this card can indicate a relationship that seems to be going nowhere, or in which one person is pulling back emotionally.

Four
(This card usually depicts a lone figure beneath a tree, surrounded by four cups.)
The Four of Cups signifies dissatisfaction with a relationship. There is nothing inherently wrong with the relationship, it has just come to the end of the "honeymoon phase." The other person is no longer perfect, and faults which you didn't see before now become apparent. Remember that no one is perfect, even though they may seem so in the beginning.
Reversed, this card can indicate a refusal to see the other person's faults. You know they are there, but refuse to acknowledge them, insisting that the other is perfect in all ways. No relationship can exist for long if one person is always on a pedastal...let the other come down to earth, and learn to love faults and all.

Five
(This card usually depicts a forlorn figure staring at over-turned cups, their contents spilling out onto the ground. Behind him are one or two upright cups.)
The Five of Cups generally indicates difficulties in a relationship, often involving separation. There is hope, however, as there is still enough feeling left to work on, providing, of course, that both parties want to make it work. There is a need to turn the focus from what's wrong (spilled away) to what's right.
Reversed, this card can indicate feeling that the relationship is not worth saving...that there is nothing left to work on.

Six
(This card usually depicts two children surrounded by six cups filled with flowers.
The Six of Cups is often refered to as "The Nostalgia Card," as it deals with issues from the past, often indicating someone from the past coming back into the Querent's life.
Reversed, this card can indicate a need to spend less time dwelling on the past, and more time looking to the future and getting on with life.

Seven
(This card usually depicts either a wizard behind seven cups (or a woman with seven cups floating above her head). The cups generally contain the following: a dragon, a faerie, gold and jewels, a castle, a rainbow, stars, and either a fish or octopus)
The Seven of Cups indicates choices to be made, often among several possibilities, all of which have emotional baggage attached. There is a need to make a decision, but often the number of choices is overwhelming.
Reversed, this card can indicate being lost in fantasies and pipe dreams, and not setting a goal to work toward.

Eight
(This card usually depicts a lone figure walking away from a stack of eight cups.)
The Eight of Cups indicates turning your back on a relationship or situation and walking away from it. This is often accompanied by feelings of loss, depression, and mourning.
Reversed, this card can indicate a need to learn to let go, to give something up, and move forward, alone, into your future.

Nine
(This card usually depicts a smiling man with nine cups on shelves behind him.)
The Nine of Cups is commonly called "The Wish Card" as it indicates the fulfillment of a cherished wish, often something you have been working toward for quite a while.
Reversed, this card can indicate a need to realize that wishes come true through hard work and dedication.

Ten
(This card usually a family (father, mother, one or two children) standing beneath a rainbow that contains ten cups. There is a castle in the distance, and they are obviously happy together.)
The Ten of Cups indicates on-going contentment and permanence in matters of the heart -- lasting happiness, a permanent relationship, etc.
Reversed, this card can indicate that there may be adversity to be weathered, which often tests the strength of a relationsip.

Page
(This card usually depicts a young person standing on the shore of the ocean, a cup in one hand, and a fish poking its head out of the cup.) The Page of Cups indicates the start of something new on the emotional level; a renewal of your capacity to love after having been hurt, starting with love of the self.
Reversed, this card can indicate being too wrapped up in the self, being afraid to step out and share yourself with another.

Knight
(This card usually depicts a young man on a horse, gazing into the cup he carries.)
The Knight of Cups is a card of romance. This is thie fairy-tale knight in shining armor, who loves for love's sake. It can also indicate a secret admirer, worshipping from afar. If the card is referring to a person, it is a somewhat romantic and poetic young man, very expressive of his feelings.
Reversed, this card can indicate someone who tends to be a bit immature emotionally. All is well unti there is a problem to be dealt with, at which point he is nowhere to be found.

Queen
(This card usually depicts a woman seated in a large sea shell, staring into a cup.)
The Queen of Cups is a loving, expressive woman with deep feelings. She reflects a need to get in touch with and express your emotions. This card also indicates a need to develop your inner life, including the ability and willingness to listen to your intuition.

King
(This card usually depicts a rather sad- or thoughtful-looking man. seated on a throne, holding a scepter and a cup. In some decks he is staring into the cup. The throne is on the shore.)
The King of Cups is a caring, sympathetic man, an excellent listener, the sort of person that everyone takes their troubles to. Often he has been deeply hurt, but instead of becoming cynical he came through it with a deeper awareness of his own feelings, and a greater undertanding of other people.
Reversed, this card can indicate someone who has put a wall around himself, and who comes across as rather cynical and unfeeling, either trying not to care, or not to show that he does. It can also indicate someone who turns to alcohol to drown their feelings.
