Root Explanation

Speculate → It is formed from "specere" (meaning to look or see) and the suffix "-ate" (indicating to cause or make). The word "speculate" means to look at something in a thoughtful way, often to form theories or conjectures without firm evidence.

Memory Tip

Think of 'looking' ('specere') thoughtfully at something to form ideas or theories — that's what it means to speculate.
