others. This week, we will begin with ‘-sion’and ‘-tion.’
tion
- if the verb ends in ‘t,’ just add ‘–ion’
- remove a final ‘e’ before adding ‘-tion’
- sometimes you must add or remove a vowel before adding ‘-tion’ (add – addition; register – registration)
- other versions: evolve – evolution
sion
- if the root word ends in –se, take off ‘e’ and add ‘–ion’
- if root word ends in ‘d’ or ‘de’, change the 'd’ to ‘s’, drop the ‘e’ and add ‘-ion’ (erode – erosion; pretend –
