Did You Know?

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.

Origin of speculate

Latin speculatus, past participle of speculari to spy out, examine, from specula lookout post, from specere to look, look at — more at spy


First Known Use: 1599
