When to drop the final "e":
* Suffixes starting with a vowel: If the suffix starts with a vowel (like "-ing", "-able", "-er"), you drop the final "e".
* Example: "hope" + "-ing" = "hoping"
* Suffixes starting with a consonant: If the suffix starts with a consonant (like "-ment", "-ful", "-ly") and the final "e" is silent, you drop the final "e".
* Example: "care" + "-ful" = "careful"
When to keep the final "e":
* Suffixes starting with a consonant: If the final "e" is part of the pronunciation, you keep it.
* Example: "use" + "-ful" = "useful" (The "e" is pronounced)
* Suffixes like "-ing" or "-ed" when the final "e" is preceded by a consonant: You keep the final "e" to avoid confusion.
* Example: "change" + "-ing" = "changing"
Special cases:
* Words ending in "ce" or "ge" followed by a suffix starting with "a", "o", or "u": Keep the "e" to keep the "c" or "g" soft.
* Example: "notice" + "-able" = "noticeable"
Ultimately, there are no hard and fast rules. The best way to learn when to drop the final "e" is to learn the spelling of the words, and look them up in a dictionary when you are unsure.
