intuit (v.) Look up intuit at Dictionary.com
1776, "to tutor," from Latin intuit-, past participle stem of intueri "look at, consider," from in- "at, on" (see in- (2)) + tueri "to look at, watch over" (see tutor (n.)). Meaning "to perceive directly without reasoning, know by immediate perception" is from 1840 (De Quincey), in this sense perhaps a back-formation from intuition. Related: Intuited; intuiting.
