The short answer
The honest short answer: the deck splits into Major Arcana (big archetypal themes) and Minor Arcana (everyday movements in four suits), upright and reversed. Learn the suits first: wands for drive, cups for feeling, swords for thought, pentacles for the material. The rest is practice. And when the question matters more than the practice, that is what an intuitive reading without cards is for.
What tarot can and cannot do
A good tarot reading names the shape of a situation, offers angles you had not considered, and gives you something true to sit with. Spreads like the three card (past, present, future) or Celtic Cross give structure to the conversation.
Cards cannot decide your future, guarantee reconciliation, or diagnose anything. A deck on the table does not change what honest reading means: no fear, no certainty for sale, no reading of anyone who did not consent to be part of your question.
