think up
Concoct from nothing
To think up is to invent or devise through mental effort: She thought up a clever excuse, Who thinks up these ridiculous rules?
The phrase emphasizes creative generation—producing something new rather than recalling something known.
It's slightly more casual than devise or conceive.
