assumably
One would think
Assumably means as one may assume or suppose—used to qualify a statement as reasonable inference rather than established fact.
The word is rare and often considered nonstandard; presumably serves the same function and is far more common: Presumably she'll arrive by noon sounds natural where assumably would sound odd.
