Left without the parent that gave it context. An orphaned thing still exists and no longer means what it did.
Greek ὀρφανώς (orphanos, bereft of parents), from Proto-Indo-European *orbho- (deprived, bereaved), cognate with Latin orbus; a thing that still exists but has lost the context that once explained it.
Left standing after the thing that gave it context is gone. An orphaned record still exists; it no longer means quite what it did.
