Most verbs are simple, but the exceptions cause the most mistakes. Master the doubling of consonants and the tricky vowel changes.
Just add -ing to the base verb.
Drop the final 'e' before adding -ing.
*Exception: be → being
Change 'ie' to 'y' then add -ing.
Do NOT change the Y. Just add -ing.
When do we double the last letter? It depends on Stress.
If the verb has 1 vowel + 1 consonant at the end, double the consonant.
Exceptions: Do not double W, X, or Y (e.g., Snowing, Fixing).
Only double if the Stress is on the last syllable.
Select the correctly spelled word.
