I beg you all pardon but absolutely every language in the world (and I'm a phylologist) has rules. It has a certain number of words which you have to learn and from there the combos are many. But you have to learn the words. Symbolical languages are even older than spoken ones but they also do have rules. Apologies to all intuition and else, I'm a very intuitive person but intuition without knowing the words is a mess. Intuition is priceless when you know your language by heart and just like with your mother tongue the right meaning comes to you naturally. But you already KNOW the language and the meanings of this word, and you didn't invent them, you learned the traditional meanings of the word. I hope I make myself clear.
I'm not considering myself an expert, I was just lucky to be a generational reader. I do keep learning my language every day.
The Fish, like every other Lenormand cards, has SPECIFIC meanings for love/relationship questions. Different ones for general, separate ones for "problems", etc. I don't think the Fish will show your mate is an alcoholic if you don't have problems with him, if you're just dating. Always stick to the question. Always!
P.S. Mlle Lenormand, from what we know from people's memoirs, was extremely definitive. I doubt she had even one sentence of the type "it could be that may be some day if you..." , very popular these days among readers. In fact, she stated events. Stated them. You will do that, this will happen then and then, etc.
P.P.S. Tarot is not different. You can't read Tarot looking at the pictures only because when you buy another deck, you will get lost. As a phylologist I find it fascinating to learn the ancient, ages, eras' old knowledge that hasn't changed. The symbols remained the same. Call me old fashioned but to me it matters that a woman or a man thousands years ago felt the same way when seeing a circle as I feel today.
