Common Core Language Standard: L.8.2c*
Pre-teaching: The “able” and “ible” suffixes are frequently confused by spellers. Both suffixes generally sound the same with the vowel taking the nasal short /ŭ/ schwa sound.
Definitions and Examples: End a word with “able” if the root before has a hard /c/ or /g/ sound (despicable, navigable), after a complete root word (teachable), or after a silent e (likeable).
Of course… What would a spelling rule be without a few exceptions?
collapsible, contemptible, irresistible, memorable, portable, probable, capable
Spelling Rule Song: (to the tune of “John Jacob Jingleheimer Schmidt”)
Base words add “able” to the end,
John Jacob Jingleheimer Schmidt,
As do word parts,
That’s my name, too.
That end in silent e
Whenever we go out-
Or with hard c or g
The people always shout,
But for all others add “i-b-l-e”.
Saying, “John Jacob Jingleheimer Schmidt.”

Practice: What’s right and what’s wrong according to the rule? Every applicable rule has been applied to eligable and agreeable citizens. The changable nature of our laws can be frustrating.
