Term (also equivalence) for the property of a word to be ambiguous. An example is "dew", which is a morning one precipitation, a rope or the 19th letter of the Greek alphabet can mean. In varietals, similar varieties are sometimes grouped under one name (homonym), although it is genotypisch are independent grape varieties. Particularly significant examples are Clevner, with which many largely unrelated grape varieties are named, and above all Malvasia with well over 50 varieties with this name ingredient. Also by the former widespread practice of confounding different varieties in the vineyard ( Mixed set ) common names were very common. Unlike the homonym, that stands synonym with different names for the same term. But there are also grape varieties that are used on the basis of a common property for several grape varieties. An example of Italy is Pagadebit ("Debt payer") for grape varieties with high yields.
