-Ible Vs. -Able

Filed under: English,Language — Brandon @ 8:00 pm

There is apparently no definitive spelling rule to determine when to use -able or -ible at the end of a word. The primary heuristic is to evaluate the root word as follows:

  • If the root is a full word, use -able.
  • If the root is not a full word, use -ible.
  • If the root is a word that ends in ‘e’, drop the ‘e’ and append -able.
  • If the root is a word that ends in ‘y’, change the ‘y’ to ‘i’ and (thus) use -ible.
  • If the root must be modified in any other way, use -ible.

There is a non-trivial number of exceptions. Also, it has been observed that most words require the -able ending, so if you have to guess, the odds favor -able.
