Do a 3 card draw online! Gives meanings, but only for individual cards and not the combined message (as would be proper for Lenormand readings) so take with a grain of salt.
Reading cards in combinations is the cornerstone of the Lenormand way and is not really optional like it would be with other decks. Lenormand’s cards are stringed together like words in a sentence that flow seamlessly within a layout. That’s why the classical layouts are Tableaus where cards are read in many sentences and structures.
Etteilla (Jean-Baptiste Alliette) was a French cartomancer active in the 18th century. He was one of the first people to popularize a system of meanings for every card in the tarot deck, including upright and reversed meanings. The Etteilla system is the foundation for most divinatory tarot today, notably for the minor arcana of the famous Smith-Waite tarot deck.
