The "I Love You" sign in one combined motion is the first sign everyone should learn - it's the heart of communication - "I love you and I want to tell you." The pinky finger by itself is the letter "I" as it is used in the American Sign Language Manual Alphabet. The index finger and the thumb make the finger-spelled letter "L". And the thumb and the pinky finger make the letter "Y" . In this way, all of the first letters of the words "I Love You" are represented. I love you. But here's a new twist: I REALLY love you! In keeping with the way each word is represented by its first letter, the first two fingers cross to form the letter R - R for REALLY. Now the sign says, I really REALLY love you! And if you really love school, you can say so in sign!
