- Exceptions or harder root words include: fictitious.
- The suffix -tious generally turns a noun into an adjective.
- How to spell the curriculum words: conscious and embarrass
Common misconception
You can hear the 'ee' in all words ending in -ious and -eous.
You cannot hear the 'ee' in words ending -geous, like 'courageous' (the 'e' is making the 'soft g' sound).
