Suffixes (age 9+)
English · Spelling & Word Study · procedural
Spell words with Latin and French suffix patterns: endings sounding like /ʃəs/ spelt -cious or -tious (e.g., precious, cautious), /ʃəl/ spelt -cial or -tial (e.g., official, essential), and words ending in -ant/-ance/-ancy vs -ent/-ence/-ency (e.g., observant/observance, confident/confidence)
What mastery looks like
- Apply the pattern that -cious follows a vowel (spacious, gracious) while -tious follows a consonant (cautious, ambitious), noting common exceptions like anxious
- Choose between -cial (usually after a vowel: special, official) and -tial (usually after a consonant: essential, partial) when spelling words with the /ʃəl/ ending
- Select -ant/-ance or -ent/-ence by checking whether the root ends in a hard c or g sound (-ant: significant) or a soft c or g sound (-ent: innocent), and by applying word-family strategies
