The spelling pattern found in long "a" and long "i" words is called the silent "e" pattern. In words with a long "a" sound, like "cake" or "bake," the "e" at the end of the word is silent but affects the pronunciation of the vowel before it, making it a long sound. Similarly, in words with a long "i" sound, such as "bike" or "smile," the silent "e" at the end also changes the vowel sound to a long "i." This pattern helps differentiate between words with short vowel sounds (without the silent "e") and those with long vowel sounds (with the silent "e").
