Here's a breakdown:
1. Silent "e" at the end of a word:
* Example: "hope" - the "e" is silent.
2. Suffix beginning with a vowel:
* Example: "-ing," "-able," "-ed," "-er," "-ous"
When to drop the "e":
* hope + ing = hoping
* hope + able = hopeable
* hope + ed = hoped
* hope + er = hoper
* hope + ous = hopeful
When to keep the "e":
* If the suffix begins with a consonant, keep the final "e".
* Example: "hope + ful = hopeful"
* Example: "hope + less = hopeless"
Exceptions:
* Words ending in "ce" or "ge" before adding "-able" or "-ous" keep the "e".
* Example: "notice + able = noticeable"
* Example: "courage + ous = courageous"
* If the final "e" is pronounced, keep the "e".
* Example: "shoe + ing = shoeing"
In summary:
* Drop the silent "e" if the suffix begins with a vowel.
* Keep the silent "e" if the suffix begins with a consonant.
* Follow the exceptions for "ce" and "ge" words and words with a pronounced "e".
