Three English Suffix Spelling Patterns

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:

  1. 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)
  2. DROPPING - Drop a final, non-syllabic <e> when adding a suffix that begins with a vowel.
  3. 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.
