The Suffix Showdown

Students compare two pairs of similar suffixes–er vs. -or and -able vs. -ible-and learn how to choose the correct one based on meaning and spelling patterns. After reviewing the guidelines, they apply the correct suffixes to example words and complete each sentence. This structured contrast helps students understand subtle morphological rules and improves spelling accuracy. The activity strengthens vocabulary precision, supports decoding of unfamiliar words, and builds confidence in selecting the correct suffix form. It provides clear, practical practice with commonly confused endings.
