Read on for more information about why we target affixes, plus goal suggestions!
What if we could teach our vocabulary learners 50 words with just a handful of magical letters? Targeting affixes in speech therapy is one way to do just that!
Personally, I’m not sure I learned much about effective morphological interventions in grad school. Since then, I’ve done a ton of digging and learning and trial and error and wanted to share a few of my takeaways with you today.
Prefixes and Suffixes lead to vocabulary growth!
Students with semantic difficulties are already at a disadvantage when it comes to vocabulary. Vocabulary development is one vital piece of the literacy development that we want to target as SLPs. Even if we focus on bang-for-your-buck Tier-2 vocabulary words, teaching one word at a time is too slow to catch them up to their peers.
Plus, it’s impossible to measure progress if you are teaching specific vocabulary. When do we say a student has mastered learning new vocabulary?
Instead, we can focus on evidence-based strategies, like teaching morphological analysis of prefixes and suffixes. Affixes are a huge clue to help students figure out word meanings, especially when they don’t have an awesome SLP perched on their shoulder 24/7. It’s effective and efficient, even for our bilingual students.
Benefits of Root Word Instruction
Understanding affixes significantly contributes to vocabulary development, reading comprehension, and other literacy skills (including spelling). Students with morphological awareness skills can use their knowledge to read (and understand!) unknown or less familiar words.
Breaking down words into their morphological parts (including identifying any prefixes or suffixes) is a helpful skill when improving both reading and written language. Many studies that I read indicated these interventions would be best for students with DLD (Developmental Language Disorder) or Dyslexia.
I’ve had great success using this type of intervention for students with language disorders with whom I might have previously targeted goals like context clues or tier 2 vocabulary. Systematic instruction with prefixes and suffixes worksheets has made a big impact!
And as far as age goes, research shows that children begin recognizing base words and morphological endings (like ‘ed’ or ‘ing’) as early as kindergarten (Wolter et al., 2009), with skills significantly increasing between 3rd and 5th grade.
For most children, root word familiarity and knowledge increases during the early elementary years (before 3rd grade). However, morphological awareness skills continue to develop through middle school, especially with more difficult affixes (including suffixes that change a word’s part of speech).
? If you want to read some research to support this type of intervention, check out Gellert et al., 2020. They provided a morphological intervention to middle school students with limited vocabulary knowledge. The students showed large short-term gains in word learning AND they retained those skills 10 months later!
And did you know that third and fourth graders accuracy in using morphological forms in their writing is predictive of their reading skills?! Knowledge of these word parts is so, so important!
What Does Effective Morphological Awareness Intervention Look Like?
In short, morphological interventions teach our students to break words apart (into morphemes) and recognize familiar word parts.
For example, the word “unrecognizable” might initially look long and confusing to students, but is made a lot easier to understand when you break it apart – “un” + “recognize” + “able”.
Components of effective morphological awareness interventions include…
? Direct teaching
? Targeted practice and…
? Immediate practice in a functional reading or writing context.
Directly teaching and practicing common affixes with prefixes and suffixes worksheets and other activities can help your students recognize them in words they read. In my opinion, this is a more effective form of “context clues” as it truly helps your students make smart guesses about what new words mean.
Some easy ways to introduce this skill into your therapy might be targeting a new affix each week for the school year, teaching affixes and base words related to themed unit you’re already doing, or breaking down words that contain affixes found in texts your students are reading in class.
Components of effective morphological awareness interventions include direct teaching (why is this important and how will it help your students), targeted practice, and immediate practice in a functional reading or writing context.
Prefix and Suffixes Worksheets & Activities for Speech Therapy – Morphological Awareness
I’ve included affix worksheets in my Themed Language Therapy Units, but now I’ve finally created a standalone product targeting affixes: the Speechy Musings Prefix and Suffix Activities for Speech Therapy – Morphological Awareness packet!
Using my affixes resource, you can teach common affixes different ways including by…
☝? Targeting one affix at a time (ex: “-er”)
✌? Breaking down a single word and discussing its affix (ex: in-visible)
PLUS activities for word building and word deconstruction
You will love this no-prep, simple product for consistent practice with your students with morphological needs. Just print and go or load it on your device for a no-print digital option!
Every page in my packet introduces a prefix or suffix word your students see every day in their classroom curriculum. Cement the meaning of the affix through multiple examples and opportunities to practice in example sentences.
It targets 50 functional and high frequency prefixes and suffixes, includes 4 different styles/levels of worksheet, comes in color and outline versions, and is just like many of my other resources:
- Visual heavy
- Systematic
- And easy to use!
Generalize into the classroom and beyond
You can extend your use of my speech materials by looking for affixes in classroom curriculum materials, novels, or Internet news articles. Challenge your students to hunt for matching prefixes and suffixes words in their regular reading materials. For students with reading difficulties, finding and matching a few letters is easier than seeking out longer words. Targeting affixes in speech therapy can easily translate to supporting our students with their educational needs.
Suffixes and Prefixes Words in Speech Therapy: Goals
When I target prefixes and suffixes, I like to use the following goals as a basic format:
- Given example words from her curriculum, NAME will state the meaning of 15 different prefixes or suffixes given no adult support.
- Given words in sentences, NAME will be able to define age-appropriate vocabulary words using prefixes and suffixes as context clues during structured activities with 80% accuracy.
You can individualize those goal by varying the context, such as within grade-level reading passages instead of at the word or sentence level.

Affixes in Speech Therapy: The Research
For students with dyslexia, teaching affixes is a vital part of providing structured literacy intervention. This study concludes that “children who understand the morphemic structure of words are far better equipped for reading and writing than those unfamiliar with word structure.” We can give our struggling students a huge boost in vocabulary, reading comprehension, and writing by targeting affixes in speech therapy.
While context clues are a great tool to teach vocabulary, sometimes context can be vague or misleading. This study discusses the advantages of including root word instruction to enhance vocabulary targets in speech therapy.
Recent Findings
In case you’re not sold yet, check out some of these findings from research:
- Children with learning disabilities use fewer morphologically complex words, they are less accurate in using affixes (Carlisle, 1996), and have increased difficulty learning morphological rules (Wiig, Semel, and Crouse, 1973).
- Morphological awareness intervention can be particularly helpful in understanding complex words found in science texts. (Zoski et al., 2018)
- A morphological intervention was given to middle school students with limited vocabulary knowledge. They showed large short-term gains in word learning and students retained those skills 10 months later! (Gellert et al., 2020)
- Beginning in 4th grade, students begin learning how to identify which part of speech a word is (noun, verb, adjective, etc…) by its word ending. For example, words that end in “ness” are nouns. (Tyler & Nagy, 1989).
- Third and fourth graders accuracy in using morphological forms in their writing is predictive of their reading skills. (Green, McCutchen & Schwiebert, 2001)
Keep in mind that the four most common prefixes (dis-, in-, re-, and un-) and suffixes (-ed, -ing, -ly, and –es) make up 97% of words containing affixes! They are a great place to start.
So next time you feel yourself wanting to teach context clues, try affixes instead and see how your students do!
If you have any questions about targeting affixes in therapy, let me know! I’d love to answer them in a future Q+A email!
Don’t forget, it would be disadvantageous to miss out on the power of teaching affixes to our students!

Love, love, love this resource! I’d been looking for a morphology resource to use with my students that have low decoding skills. The visuals and short sentences on these pages have been a huge support for them. Thank you!
Naranja dulce
This resource is one of my go-to tools for students working on vocabulary (building foundational skills while still appealing to my older students). It’s beautifully designed and includes so many features for explicit teaching and structured practice! Thank you so much for putting this together, Shannon!
Holly the SLP
This is *exactly* what I’ve been trying to create myself. It’s been hard for me to find a resource that is complete enough for me to use; I always end up trying to cobble together different sections and pages that I like. This one is it though. Speechy Musings always comes up with fun *and* functional resources. My summer session kiddos did really will with this over 4 weeks, I really can’t wait to see what they do with more time next year 🙂
