Derivational Morphemes in Action: A Story

Let’s look at Max, a 7-year-old with ADHD, who struggles with reading. Derivational morphemes can be a hurdle in his learning journey. Here’s how it might play out:

Max sees a new word: He reads “singer” but only recognizes the word “sing.”
Confusion sets in: Max doesn’t understand how “sing” changes when “er” is added.

Max practices: He uses other words like “teach” to “teacher” to see how the pattern works.
Success builds confidence: Max gets more comfortable with recognizing how small changes impact words.

These small victories help Max grow his reading skills, one morpheme at a time.
