GRE pro tips:
Opaque is an interesting word because it has several distinct—but related—meanings. It can refer to an object that is unclear in that it does not let light through, such as an opaque rock or stained glass. Likewise, it can refer to a subject or topic that is unclear in that it is difficult to understand or enigmatic, such as poetry or theoretical physics. Lastly, it can be used to describe someone who has difficulty understanding things, as if their eyes or brain are unclear.
Try to tie these definitions together to remember them better. A subject (like theoretical physics) might be so opaque that you may as well view it through an opaque window—it’s that hard to understand. Or, someone might be so opaque that he may as well be looking through an opaque window or lens—he has such a hard time seeing and understanding things.
