Conjecture is formed from "con-" (meaning together) and "jacere" (meaning to throw). The word describes the act of throwing together ideas or forming an opinion based on incomplete information.

Memory Tip

Think of 'throwing together' ideas when you make a guess or opinion — that's what conjecture means.
