Related to or capable of extrusion; tending to extrude or push outward.
From extrude plus the Latin suffix -ile (meaning 'relating to' or 'capable of,' as in 'mobile,' 'hostile,' 'sterile'). This is a rare variant form of the more common -ible or -able.
This is a wonderfully obscure word that highlights how English has multiple ways to express the same idea—compare 'extrudable,' 'extrusible,' and 'extrusile.' Most of these technical variants are forgotten or used only in specialized fields, but they all reflect how English speakers kept experimenting with different Latin and French suffixes!
