Is there a word that means I understand what you're saying, but does not mean that I comprehend it?
For instance: "Given the big-O notation, we can calculate the approximate time the algorithm will take."
That is perfect English, and broken up word by word (Save "big-O"), it can be understood. However, the actual meaning of the sentence may not be.
So basically, is there a word that says I understand each word, while not doubling to mean I understand the idea?
Edit: I'm not looking to say I don't understand you, rather just one word that doesn't double to mean the other, and doesn't have a negative connotation. So expound, incomprehensible, and so on are not what I'm looking for.
J L V has put it the most elegant, "You're looking for a single word describing that while you both HEARD (audibility) and UNDERSTOOD (meaning) every single word in that sentence you still weren't able to get the 'big picture'."
