Mōld or Mōuld1, n.
n. [A-S. & O. Fr. molde, Icel. mold, Dan. muld, Sw. mull, mylla, D. mul, L. Ger. & N. H. Ger. mull, A-S. myl, O. H. Ger. molt, molta, Goth. mulda, allied to Goth. malan, Lat. molere, to bruise, grind.] [The prevalent spelling is mould; but as the u has been omitted in the other words of this class, as bold, gold, old, cold, &c., it seems desirable to complete the analogy by dropping it in this word, as was done by Spenser, South, and many others. The omission of the u is now very common in America.]
