Capable of being extruded or forced out; able to be squeezed through an opening.
From extrude (Latin ex- 'out' + trudere 'to thrust') plus -ible, an alternate form of the -able suffix borrowed directly from Latin. The -ible ending appears in words like 'flexible' and 'accessible.'
There are two suffixes for this idea—'extrudable' and 'extrusible'—and they mean nearly the same thing, but 'extrusible' sounds more formal and Latin-y! English often inherited both versions because we borrowed from French (-able) and Latin (-ible) during the Middle Ages, so we ended up with this redundancy.
