Examples:

“Directed by Ryan Coogler, ‘Black Panther: Wakanda Forever’ ... covers a lot of ground, paying tribute to the late Chadwick Boseman and his role of T’Challa, catching up with characters new and old, plus introducing a new foil in Namor (Tenoch Huerta Mejía), a fan favorite from the comic books. However just as the original 2018 ‘Panther’ offers an emotional path to understanding family legacy for T’Challa, the sequel puts a similar spotlight on his sister, Shuri (Letitia Wright), while giving fans a chance to speculate where the new Black Panther might go next.” — Brian Truitt, USA Today, 12 Nov. 2022

Did you know?

It might be said that what separates our species from others is our tendency “to meditate on or ponder a subject.” That's the original 16th century meaning of speculate. It's a use not too distant from today's most common sense, which also involves the mind and thinking: when someone speculates about something, they think and make guesses about it, often forming ideas or theories when there are many things not known about the thing. But the origins of speculate lie not in thinking but in looking—the word comes from Latin specere, meaning “to look,” or “to look at.” We don't have to look far to find other specere descendants, and we'll point them out here with some italics: a cursory [inspection](https://www.merriam-webster.com/dictionary/inspection) reveals [spectacle](https://www.merriam-webster.com/dictionary/spectacle), [spectrum](https://www.merriam-webster.com/dictionary/spectrum), [specimen](https://www.merriam-webster.com/dictionary/specimen), and [perspective](https://www.merriam-webster.com/dictionary/perspective).
