The ten terms you see are in a simple "alphabet substitution" code. All this means is that one letter represents another. For example, in a given puzzle, the letter "B" might be represented by the symbol "T," while a "T" might look like an "A," and and "A" like an "R." As a result, the word "BAT" would be written as "TRA." The title of the puzzle tells you what all ten terms have in common, and the substitution code is the same for all ten of the words. Hint--it is easier to crack the code if you can think of a term that is likely to be on the list and includes at least one instance where the same letter is used twice, then scan the list to see if any of the given words fit the pattern. So, if the catagory is "Fruit" and one of the items on the list is "GRRPD," you could probably guess that the word is "APPLE"--the double letter gives it away.
