This lesson is not too hard. Again, more memorization. We are introduced to many word endings and how to deal with homonyms or words that sound alike but have different meanings. And, as always, more arbitraries.
Soundalike rule #1 - If one of the two words is spelled with a long A vowel. write the word utilizing the long A and an AE with the other.
EX= Mail = MAIL Male= MAEL
Soundalike rule #2 - If neither word is actually spelled with a long A, but has a long A sound, write the one spelled with a EA as AE and the other with a long A.
