Solution: First thing to notice is that each word is two letters long and there are two bars in each set. Each letter in the word is treated separately, and the connector bars represent the distance in the alphabet between corresponding letters in connected words. A dot represents one letter, and a stripe represents 5 letters. For example, in the words "UP" and "IS", the letters "P" and "S" have 2 letters between them in the alphabet ("Q" and "R"), and "U" and "I" have 11 letters between them ("JKLMNOPQRST"). This is marked on the two bars between them as 2 (2 Dots) and 11 (2 Stripes + 1 Dot). Using this method, one can solve for the blurred out words: "MY", "AT", and "AM". Continuing in this way, the only possible center word is the solution: "OF".
