Etymology

Origin of presupposition

First recorded in 1530–40; from Late Latin presupposition-, stem of presuppositio, equivalent to Latin praesupposit(us) (past participle of praesupponere ) + -iō -ion ( def. ); presuppose ( def. )

Explanation

When you assume some fact at the very beginning of an argument, that's presupposition. If a book critic decides that a novel is intended for young adult readers before writing her review, she makes a presupposition. When you presuppose, you make an assumption about something from the start, and presupposition is the action of presupposing. Your presupposition about how terrible a movie is going to be might color your actual experience of watching it, for example. The noun presupposition comes straight from the Medieval Latin praesuppositionem, which combines prae-, "before," and suppositio, "suppose."
