-ible
Makes adjectives capable
A suffix forming adjectives that mean capable of or susceptible to something: edible, visible, reversible.
It attaches mainly to Latin-derived roots and alternates with -able, which is more productive in modern English.
The choice between them follows no clear rule—you simply have to know which words take which suffix.
