1. Adding “ed” and “ing”

2. When making a word past tense, you usually add “ed to the word without changing the way the base word is spelled.
Example: cover = covered
Sometimes, you have to add “ing” to words so that they make sense in a sentence. Usually, you do not have to change the base words spelling.
Example: visit = visiting

3. If the base word ends in “e”, you will drop the “e” before adding “ed” or “ing”
Examples:
Amuse = amusing
Decide = decided

4. If the base word only has one syllable and it ends with a vowel and single consonant, you will double the last letter before adding “ed” or “ing”
Examples:
Stop = stopped vc
Plan = planning

5. If the word has one syllable and ends in one vowel and an x, you will not double the x like you do the other consonants.
Example:
Mix = mixed vc
Fix = fixing
