Originally a theological word for spiritual perception; later, instinctive understanding

from Middle French intuition

Modern English
intuition

Picture a Roman observer leaning forward—not merely seeing something, but watching it closely enough to understand what it means. Latin intueor meant “to look at” or “to consider,” built from in-, “at or in,” and the watchful verb tueor; that same protective root also gave English tutor, someone who watches over a learner. By the mid-15th century, Medieval Latin intuitiō had become Middle French intuition and then English intuition, first carrying a distinctly theological sense of spiritual perception. The modern verb intuit arrived much later: in 1776 it could mean “to tutor,” while its familiar sense, “to know directly without reasoning,” appeared around 1840, associated with Thomas De Quincey. So intuition is not originally a mystical stomach signal at all—it is the mental afterimage of looking hard enough that thought seems to arrive before explanation.
