Base Word +ed or +ing

1) Drop the final 'e' before adding -ed or -ing.
2) 1+1+1 words have one vowel, one syllable, and one end consonant these words require you to double the end consonant before adding -ed or -ing.
3) Change "lonely y" to 'i' before adding -ed, but not when adding -ing. Never change a 'y' that is part of a vowel team (oy, ay, ey, uy).
4) Make no change.
