Here's why:
* Silent "e" is a signal: The silent "e" at the end of a word indicates that the preceding vowel has a long sound (like "bake", "hope", "ride").
* "-ing" changes pronunciation: Adding "-ing" can change the pronunciation of the word, making the vowel sound short (like "baking", "hoping", "riding").
* Maintaining sound: Dropping the "e" keeps the pronunciation consistent and avoids an awkward double "e" at the end of the word.
Example:
* Bake + ing = Baking
* Hope + ing = Hoping
* Ride + ing = Riding
However, there are a few exceptions:
* Words ending in "ge" or "ce": You keep the "e" to maintain the soft "g" or "c" sound. For example, "notice" + "ing" = "noticing", "manage" + "ing" = "managing".
* Words ending in "ie": You change the "ie" to "y" before adding "-ing". For example, "lie" + "ing" = "lying".
