Surface Forms
Morphology
Lagrangian = Lagrange (semi-transparent) = Lagrange + ian
Formed from the proper name 'Lagrange' plus the adjectival suffix '-ian'; the morphological formation is clear but the meaning is domain-specific and tied to the eponym.
Etymology
Lagrangian comes from the name of the French mathematician Lagrange and the ending -ian, which means 'of or relating to', as in Newtonian. So Lagrangian means 'relating to Lagrange's methods' and is used for the mathematical approach he gave to physics and mechanics.
