manipulation (n.)

by 1730, a method of digging ore, from French manipulation, from manipule "handful" (a pharmacists' measure), from Latin manipulus "handful, sheaf, bundle," from manus "hand" (from PIE root *man- (2) "hand") + root of plere "to fill" (from PIE root *pele- (1) "to fill"). Sense of "skillful handling of objects" is attested by 1826; extended 1828 to "handling or managing of persons," especially to one's own advantage.
