Count the number of times that the letter F appears in the following sentence: 


“Finished files are the result of years of scientific study combined with the experience of years.”

How many did you find?


ANSWER:  The letter F appears 6 times in the above sentence, but most people say three. Why? We often don’t correctly process the word “OF” for two reasons. First, the letter F usually makes the “f” sound, like in “fox”. However, in the word “of”, it makes a “v” sound. Second, you have probably read the word “of” so many times in your life that you process it as one unit, overlooking the second letter/ sound.
