"Speculate" was adopted into English in the late 16th century from Latin "speculatus," the past participle of the verb "speculari," which means "to spy out" or "to examine." "Speculari," in turn, derives from "specula," meaning "lookout post," and ultimately from the Latin verb "specere," "to look (at)." Other conspicuous descendants of "specere" are "inspect" and "suspect." Some less obvious descendants are the words "despise," "species," "specimen," and, as you may have speculated, "conspicuous."
