Luna is absolutely right. Lenormand is a language where we translate symbols into phrases. Each card carries multiple meanings which can be overwhelming for new readers. It's perfectly fine to consult reference materials for your reading. We've all been there. Rana George's book is a good one to start with.
I'd also suggest that you define a clear system to guide yourself.
Intuition is simply an ability to instinctively understand something without conscious reasoning. It can be trained and developed as you keep connecting with your inner source of wisdom and knowledge. Have fun learning and exploring the cards!
