Capable of being fed or able to be used as food.
From 'feed' (Old English 'fēdan') with the suffix '-able,' which means 'capable of being' and comes from Old French '-able,' derived from Latin '-abilis' (capable of).
The '-able' suffix is borrowed from Latin through French, which is why English has two ways of saying almost the same thing: 'readable' (from Latin-influenced '-able') and 'you can read it' (good old Germanic English).
