etymonline
meditation (n.)
c. 1200, meditacioun, "contemplation; devout preoccupation; private devotions, prayer," from Old French meditacion "thought, reflection, study," and directly from Latin meditationem (nominative meditatio) "a thinking over, meditation," noun of action from past-participle stem of meditari "to meditate, think over, reflect, consider," from a frequentative form of PIE root *med- "take appropriate measures." Meaning "meditative discourse on a subject" is early 14c.; meaning "act of meditating, continuous calm thought upon some subject" is from late 14c. The Latin verb also had stronger senses: "plan, devise, practice, rehearse, study."
