The word "speculate" originates from Latin speculatus (past participle of speculari, "to spy out" or "observe"). It initially referred to observing from a distance (like a speculator, a Roman scout). Over time, it evolved metaphorically to mean "theorizing" (mentally observing possibilities) and later gained financial connotations (risky observation of market trends). The core logic ties "looking" to "hypothesizing" and "gambling."
