There are three basic suffixing patterns in English.
These patterns are listed below, with links to the Real Spelling animations that explain and illustrate each pattern:
- DOUBLING- Double the final consonant letter when adding a suffix that begins with a vowel to a base that ends with a single consonant (sound or letter) preceded by a vowel spelled with a single letter. (Advanced DOUBLING: Double the final consonant letter when adding a suffix that begins with a vowel to a stressed syllable spelled with one vowel letter)
- DROPPING - Drop a final, non-syllabic <e> when adding a suffix that begins with a vowel.
- CHANGING- Change a final <y> to <i> when adding a suffix to a base that ends with a <y> that is not part of a vowel digraph.
Teaching these suffixing patterns to clients with language processing difficulties is likely to require:
1) explicit teaching of the pattern, perhaps introduced with a discovery-learning activity in which the client sorts suffixed words in to two groups: those that are examples of the pattern and those that are not.
2) the initial use of a rubric or checklist that allows the client to check off the structural elements required for the suffixing pattern to apply; (Attached is a rubric for the doubling pattern.)
3) practice that begins with guided, supported practice using the rubric or checklist and moves toward independent application in which the process is internalized.
