Citations for sagacity
Never before that night had I felt the extent of my own powers--of my sagacity. I could scarcely contain my feelings of triumph. To think that there I was, opening the door, little by little, and he not even to dream of my secret deeds or thoughts. Edgar Allan Poe, "The Tell-Tale Heart," The Pioneer, January, 1843
So swift, silent, and furtive were his movements, like those of a trained blood-hound picking out a scent, that I could not but think what a terrible criminal he would have made had he turned his energy and sagacity against the law, instead of exerting them in its defense. Arthur Conan Doyle, "The Sign of the Four," Lippincott's Monthly Magazine, February, 1890
Origin of sagacity
Sagacity can be traced to the Latin sagācitās meaning "wisdom." It entered English in the mid-1500s.
