Lesson 7 introduces ou, oo, sh, ar, and the 5 jobs of silent 'e'.
These jobs are:
1. The first job of silent 'e' is to enable the previous vowel to make its long vowel sound.
2, Since English words rarely end in 'u' or 'v', silent 'e's second job is to end the word for these letters.
3. The third job of silent 'e' is to follow 'c' and 'g' allowing them to say their second sound.
4. Every syllable needs a vowel. When the second syllable lacks a vowel, silent 'e' is added to the end.
5. English isn't perfect. Sometimes there is a silent 'e' for no reason at all. Luckily, these words are not too difficult to memorize. A word list is provided in the purple manual.
