The word “abstract” might remind you of modern art. An abstract painting, for example, does not normally contain recognizable objects. In other words, we can't look at the painting and immediately say that's a house or that's a bowl of fruit. To the untrained eye, abstract art looks a bit like a child's finger-painting--just brightly colored splotches on a canvas.
Avoid abstract language it won’t help the reader understand what you're trying to say!
