To treat as external or external to; to place or consider something as being outside rather than inside.
From external (Latin externus) + -ate (Latin suffix creating verbs). This is a rare, specialized term developed to create a verb form parallel to 'internate'.
While 'externate' is extremely rare in modern English, it shows how productive Latin suffixes allow us to create new words—we can 'externate' a problem by treating it as someone else's responsibility, though we might just call it 'externalizing' instead.
