What do square, conjunction, trine and sextine mean?

* All together, these are called aspects. The aspects are numerical representations of the relationships between the planets. Huh? you say? There are distances between the planets and depending on that distance, the planets interact in different ways. The conjunction is the closest one, here the planets sit together- withing 8-10 degrees of each other. Because of the closeness their energies combine to make one so their meanings intertwined. An example in your chart is your Mercury conjunct Venus. This gives you a charming way of expressing yourself, as Mercury is your way of expressing yourself and Venus is beauty, charm. This is a good aspect for sales or trying to convince people. The sextile is the next closest and represents free flowing communication between the two. Venus sextile Uranus gives you a unique sense of style, and maybe your values are a little original to you. Next is the square, this is one that needs to be worked on. The energies are in a tension relationship, they each have a specific energy and it is at cross purposes with the other. Venus square Saturn in your chart gives you a sense of being judged. And because the aspect is square you are uncomfortable and feel the judging is not favorable to you. You feel lacking in whatever is valued, that you are not good enough. Trine is the next aspect. This is a gift of ease between the two planets involved. Their meanings flow easily together and the area these planets correspond to are easy for you- a gift. Your Sun trines your Moon; this is a very nice comfortable aspect dealing with your innermost self flowing easily with the way you express your emotions. It also refers to how you see the relationship between your parents. It is balanced, relaxed and consistent. The last major aspect is the opposition. It is what it says it is- two planets with opposing energies pulling you in both directions. The goal here is to reconcile them and find a compromise. No oppositions! There are minor aspects that different astrologers use or not, including the semi square, inconjunct, quintile, but don't worry about them. There is enough to do with working through the major aspects. Your list looks like it came from cafeastrology? Did you read through the interpretations given there?
