1776, "to tutor," from Latin intuit-, past participle stem of intueri "look at, consider," from in- "at, on" (from PIE root *en "in") + 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.

mid-15c., intuicioun, "insight, direct or immediate cognition, spiritual perception," originally theological, from Late Latin intuitionem (nominative intuitio) "a looking at, consideration," noun of action from past participle stem of Latin intueri "look at, consider," from in- "at, on" (from PIE root *en "in") + tueri "to look at, watch over" (see tutor (n.)).

early 15c., tuicioun, "protection from enemies, care, custody, safekeeping" (senses now obsolete), from Anglo-French tuycioun (13c.), Old French tuicion "guardianship," from Latin tuitionem (nominative tuitio) "a looking after, a caring for, watching over, protection, guardianship," from tuitus, past participle of tueri "to look after" (see tutor (n.)).

The meaning "action or business of teaching pupils" is recorded from 1580s (on the notion of the tutor as a guardian). The meaning "money paid for instruction" (1828) probably is short for tuition fees, in which tuition refers to the act of teaching and instruction (a sense attested from 1580s). Related: Tuitional.
