-ary, -ory, -ery - choose the right one

Thanks to Shireen Shuster from www.spellzone.com and her Spelling Essentials book: "When you proofread, think about how you have seen the word written before. Does the word look right when you write it on paper? Look at the three possible spellings for each Spelling Word. Write the spelling that looks correct. When adding the suffixes –ary, -ery, and –ory, there are often no sound clues to help you decide whether to use an a, an e, or an o. Sometimes these two clues might help: Use the base word as a clue: brave, bravery. Use a related word as a clue: imagination, imaginary."
