Root Explanation

Conjectural → It is formed from "con-" (meaning together) and "jacere" (meaning to throw). The word refers to ideas or conclusions that are thrown together based on incomplete information or speculation.

Memory Tip

Think of ideas being 'thrown together' ('con-' and 'jacere') to form a guess or hypothesis, which is what conjectural means.
