Usage: usually capitalized L
Etymology: Joseph L. Lagrange died 1813 Italian-born geometer and astronomer in France + English -ian
: any of five points at which a small object (as a satellite) will be in gravitational equilibrium with and will move in a stable configuration with respect to two large bodies (as the earth and the sun)
