To have as one's own and answer for it — possession with responsibility inside it; sovereignty's quiet verb.
Old English āgen (one's own), the past participle of āgan (to have, possess, owe); the same root that gives owe, so having a thing as one's own and answering for a debt were once the one word.
To hold a thing as one's own and to answer for it in the same breath — possession that carries its responsibility inside it rather than beside it.
