under weigh

O.E. wegan "find the weight of, have weight, lift, carry," from P.Gmc. *weganan (cf. O.S. wegan, O.Fris. wega, Du. wegen "to weigh," O.N. vega, O.H.G. wegan "to move, carry, weigh," Ger. wiegen "to weigh"), from PIE *wegh- "to move" (cf. Skt. vahati "carries, conveys," vahitram "vessel, ship;" Avestan vazaiti "he leads, draws;" Gk. okhos "carriage;" L. vehere "to carry, convey;" O.C.S. vesti "to carry, convey;" Lith. vezu "to carry, convey;" O.Ir. fecht "campaign, journey"). The original sense was of motion, which led to that of lifting, then to that of "measure the weight of." The older sense of "lift, carry" survives in the nautical phrase weigh anchor. Fig. sense of "to consider, ponder" (in ref. to words, etc.) is recorded from 1340.
