Suffixes
Apply suffix spelling rules that require changes to the root word: dropping final -e before vowel suffixes, changing -y to -i, doubling final consonants in short-vowel words; use suffixes -ment, -ness, -ful, -less, -ly
Quick check
When the learner adds an ending like "-ing" or "-ed" to a word, do they know when to drop a silent "e," double the last letter, or change a "y" to an "i" — for example, "running," "baked," or "happily"?
Ask this to see whether the topic is secure.
