Answer Key
Able / Ible Rules
1. Able is generally added to the end of roots that are full words.
2. Able is added to the end of roots if the root is a full word with the final e dropped.
3. The ending should usually be -able if the base word ends in a i (or sometimes when
the original word ends in a y and it is changed to a i when a suffix is added).
4. The ending is usually -able when the base has other forms with the sound of long a.
5. The ending is usually –able if the base ends in a hard c or g sound.
6. Ible is generally added to the end of roots if the root is not a word.
7. The ending should usually be –ible if the base ends in ns.
8. Ible is used when the base ends in –miss.
9. The ending is usually –ible if the base ends in a soft c or g sound.
Underline the correct suffix, then write the word with the suffix on the line and the
number of the rule that it follows.
