  • Write "breakable," "comfortable," and "washable" on the board.
  • Ask students what they notice about this list of words. Guide them towards the idea that all three words end in "able."
  • Explain that "-able" is a suffix, or a group of letters that comes at the end of a root word and changes its meaning.
  • Explain that a root word doesn't have a prefix or suffix. List some examples like the words color, form, and art. Show how adding "-ful" (which means "full of") to "color" changes its meaning.
