Tarot Foundations: The 78-Card Structure

Think of the deck as a two-speed gearbox. The 22 Major Arcana — numbered 0 (The Fool) through 21 (The World) — deal with the big, slow-moving forces in a situation: character, fate, and long-arc change. When Majors dominate a spread, the reading is pointing at something significant that is unlikely to resolve quickly.

The 56 Minor Arcana handle daily texture: decisions, moods, relationships in motion, practical obstacles. They do not mean less — they mean closer to the surface. A reading heavy with Minors usually describes a situation still in flux, where your choices carry real weight.

A.E. Waite, whose 1910 companion text remains the foundation of Rider-Waite-Smith (RWS) interpretation, treated the Majors as carrying the deeper symbolic freight of the tradition, while acknowledging the Minors as essential to practical reading (Waite, 1910). Historian Robert M. Place traces this two-tier structure back to the deck's Italian Renaissance origins, when the trump cards (Majors) were literally a separate trump suit layered onto a pre-existing four-suit game pack (Place, 2005).

The Majors run in a numbered sequence that many readers treat as a narrative arc — sometimes called the Fool's Journey — in which The Fool (0) moves through encounters with different archetypes until reaching integration at The World (21). You do not have to accept any metaphysical claim about that journey to find it useful: the sequence gives you a memory scaffold.

A few orientation notes:

• Cards 1–7 (Magician through Chariot) tend toward outer-world themes: will, authority, choice, momentum.
• Cards 8–14 (Strength through Temperance) tend toward inner-world themes: patience, solitude, transformation.
• Cards 15–21 (Devil through World) tend toward larger forces, crises, revelation, and completion.

Note on numbering: In the RWS deck, Strength is VIII and Justice is XI. The Thoth deck (Aleister Crowley, 1944) swaps them — Justice (called Adjustment) becomes VIII and Strength (called Lust) becomes XI. Marseille decks typically follow the older ordering that Crowley restored. This matters when you cross-reference older sources. See the [learning-the-major-arcana] guide for card-by-card detail.

The Minor Arcana divide into four suits, each containing 14 cards: Ace through 10 (the pip cards) plus four court cards (Page, Knight, Queen, King).

Suit	Element	Broad Domain
Wands	Fire	Drive, creativity, ambition, projects
Cups	Water	Emotions, relationships, imagination
Swords	Air	Thought, conflict, communication, decision
Pentacles	Earth	Material life, work, body, money

Elemental assignments are consistent across RWS and Thoth, though Thoth calls Pentacles Disks and applies a more rigorous system of elemental dignities — where adjacent cards in a spread can strengthen or weaken each other based on their elemental pairing. The [reading-cards-in-combination] guide covers elemental dignities in full.

Pip cards (Ace–10): Aces are pure elemental seed energy; the numbered cards trace the suit's development from initiation (2–4), through challenge and turning point (5–7), to resolution or excess (8–10). The Ten of Wands, for example, is fire pushed to the point of overload — ambition become burden.

Court cards (Page, Knight, Queen, King): Courts are the most context-dependent cards in the deck. They can represent real people in the querent's life, the querent themselves at a particular stage, or a behavioural mode being called for. The [learning-the-court-cards] guide treats them in depth.

A tarot reading is a structured interpretive procedure, not a passive reception of messages. The steps are:

1. Frame a question. A well-formed question focuses the spread. Vague input produces vague output. See [how-to-phrase-a-tarot-question] for the grammar of useful questions.
2. Choose a spread. A spread assigns each card position a specific meaning before any card is drawn — position 1 might be 'the core issue', position 2 'what is hidden'. The positions do interpretive work. See [learning-tarot-spreads] for how to choose.
3. Draw cards. Cards are assigned to positions in order.
4. Read positions. Each card is interpreted through its position meaning. The Ten of Wands in 'what to release' reads differently from the same card in 'what is driving you'.
5. Synthesise. The positions are then read in relation to each other — narrative, contrast, elemental dignity — to produce a coherent response to the original question. This synthesis step is where reading skill actually lives.

A single-card draw (see the [single-card] spread) is the simplest version: one question, one position, one card. The [celtic-cross] spread is the most information-dense common layout, with ten positions covering context, obstacle, past, future, self-perception, and outcome.

Most tarot content online treats the Rider-Waite-Smith deck as if it were tarot itself. It is not — it is one of three major living systems, each with distinct rules.

Rider-Waite-Smith (1909): Illustrated pip cards (the Ace–10 scenes are unique to RWS and its derivatives), reassigned Strength/Justice numbering, rich Golden Dawn symbolism filtered through Waite's selective disclosure. Waite deliberately withheld some Golden Dawn material in keeping with his oath of secrecy, which is why his 1910 Pictorial Key is sometimes frustratingly coy (Waite, 1910).

Thoth (Crowley/Harris, 1944): Returns to older numbering (Strength as Lust = XI, Justice as Adjustment = VIII), renames several cards, and builds in a formal system of astrological and elemental correspondences that function as an interpretive grammar rather than decoration. Court cards are renamed: Princess, Prince, Queen, Knight (where Knight = King).

Marseille (pre-18th century): Unillustrated pip cards (geometric arrangements of suit symbols, no scenes). Interpretation relies on number symbolism, suit, and position rather than pictorial narrative. Place (2005) identifies the Marseille pattern as historically prior to both RWS and Thoth, rooting it in the Italian game decks of the 15th and 16th centuries.

This guide teaches in RWS but flags Thoth and Marseille differences at each decision point. If you own a Thoth or Marseille deck, the structural framework on this page applies — the suit meanings, the Major/Minor split, and the reading procedure — but card-specific details will differ.

Two mechanics extend the basic 78-card structure significantly:

Reversals (cards dealt upside-down) are not simply 'bad news'. Mary K. Greer identifies four distinct interpretive modes for reversed cards: blocked energy, internalised energy, the card's energy in delay, and the card's shadow expression. Each mode produces a different reading. See [reading-reversals] and the full [/reversals] reference for the framework. Your [your-first-tarot-reading] guide walks you through whether to use reversals at all when starting out.

Combinations — reading cards in relation to each other rather than in isolation — are where intermediate skill develops. Figure gaze (which direction a court card faces), elemental dignity (whether adjacent elemental energies support or clash), and narrative arc across positions all feed into combination reading. The [reading-cards-in-combination] guide covers this systematically.
