Getting started with tarot number meanings

Quick answer

The numbers in the Minor Arcana can be read as stages of one theme: beginning, choosing and adjusting, moving towards a result, a turning point or completion. The specific meaning still depends on the suit and the context of your question.

Read the number with the suit

Take the threes: in Wands, Cups, Swords and Pentacles the same idea of "development" lands on action, relationship, understanding and shared resources respectively.

A way to practise

Pick the four cards that share a number, compare their imagery, keywords and everyday situations, and build your own reference notes.
