What does presumptively mean?
Presumptively means on the basis of a presumption or accepted assumption, normally where evidence has not yet established the contrary. Its use suggests a working basis that may be revised if new information appears, as when a document is presumptively authentic or a person is presumptively innocent. The word is especially associated with legal, academic, and formal administrative contexts. It should not be confused with presumably, which more commonly means probably or as may be expected. Presumptively is therefore more precise when a recognized default, inference, or legal presumption is involved. Though less common in everyday speech, it is useful because it distinguishes a conclusion resting on an established assumption from a general expression of likelihood. Its formal character also signals that the statement has a qualified, provisional basis rather than expressing absolute certainty.

Where does presumptively come from?
Presumptively was formed in English by adding the adverbial suffix -ly to presumptive. The word family ultimately comes through Old French from Latin praesumere, a compound of prae-, meaning before or in advance, and sumere, meaning to take. The Latin verb conveyed the idea of taking something in advance and therefore came to mean to assume or suppose. Its relatives include presume, presumption, and presumptuous.
