Silent Letters and Advanced 'sion' Words Spelling List
Learning words with the 'sion' ending pattern (pronounced /ʃən/) presents an important challenge for developing spellers. This collection focuses on common words that use this spelling pattern, which often appears in words related to actions, states, or processes.
Word List
Here are 20 common words that use the 'sion' spelling pattern:
- mansion
- expansion
- tension
- extension
- pension
- dimension
- mission
- admission
- passion
- compassion
- session
- succession
- concession
- procession
- confession
- profession
- depression
- expression

Educational Standards Alignment
These words align with several Common Core Standards. Particularly relevant standards include:
- CCSS.ELA-LITERACY.L.3.2.F: Use spelling patterns and generalizations (e.g., word families, position-based spellings, syllable patterns, ending rules, meaningful word parts) in writing words.
- CCSS.ELA-LITERACY.L.4.2.D: Spell grade-appropriate words correctly, consulting references as needed.
These standards are particularly applicable because the 'sion' spelling pattern represents a more advanced phonics concept that students typically master in upper elementary grades. The words in this list help students recognize and apply the pattern where 'sion' creates the /ʃən/ sound, a crucial spelling generalization that appears frequently in academic vocabulary.
Teaching Tips
When introducing these words, it's helpful to point out that many of them are derived from base words ending in '-d', '-de', '-s', '-ss', or '-t'. For example, 'extension' comes from 'extend', and 'admission' from 'admit'. Understanding these relationships can help students both spell the words correctly and comprehend their meanings more deeply.
Differentiation Strategies
For younger or struggling students, you might want to start with shorter, more familiar words like 'mission' and 'session'. More advanced learners can tackle longer derivatives like 'succession' and 'compassion', while also exploring the relationships between base words and their 'sion' forms.
Assessment Opportunities
These words provide excellent opportunities for both formative and summative assessment. Consider using them in context-based activities, spelling tests, or vocabulary exercises that require students to demonstrate both spelling accuracy and meaning comprehension.
