**NOTE: There is another question asking "What is a Lattice?" but when reading the question, it has to do with programming, and that is not what my question has to do with. The answer provided to that question didn't answer MY question either, so please don't list this as a duplicate.**

I have been researching set theory and I've come across "lattices". Looking at the wikipedia article and some other articles, it makes it so confusing and I can't understand anything. I tried looking for videos or articles or anything explaining lattices, but to no avail. Help? Can anyone explain to me in detail the basics of lattices, or, provide an article that explains them?
