-able,  -ible
It is often very difficult to know whether to write -able or -ible as the suffix of a number of words. Here is a list of common words ending in -able, followed by a second list ending in -ible.

-able

acceptable accusable achievable adaptable adorable advisable  agreeable amendable breakable  bribable challengeable changeable chargeable  charitable confrontable communicable conceivable crushable curable definable desirable detestable diminishable eatable endurable explainable excitable extinguishable forgivable flammable hospitable immovable interpretable impenetrable impressionable irreconcilable justifiable  lovable

manageable modifiable marriageable  movable notable noticeable pardonable palatable persuadable  pleasurable predictable preventable probable  pronounceable questionable reasonable recognisable  reconcilable reformable regrettable  relievable removable replaceable sal(e)able satisfiable  scalapie serviceable smotherable supposable suprassable sustainable  tenable tolerable traceable transferable uncontrollable undeniable vulnerable

-ible

accessible admissible audible collapsible combustible comprehensible convertible corruptible contemptible  convincible defectible divertible  divisible defensible digestible discernible  edible eligible

expansible expressible  indelible inexhaustible intelligible  irresistible negligible perceptible permissible  repressible reversible responsible sensible suppressible susceptible tangible transmissible  visible

NOTE:    The verbs ending in -e drop the letter when -able is added, except after a soft c (s), after a long g (z) : peaceable, changeable, etc.                                                                                      The verbs ending in y change their last letter to i (justify becomes justifiable). Also note that the words like likable, namable, salable may be spelled with or without an e. Certain dictionaries recommend the dropping of the e.
