| gondola | 1. A long, narrow boat with a high prow and stern, used in the canals of Venice. A gondola is usually propelled by one or two oarsmen who stand facing the prow, or by poling. A gondola for passengers has a small open cabin amidships, for their protection against the sun or rain. A sumptuary law of Venice required that gondolas should be painted black, and they are customarily so painted now. 2. A flat-bottomed boat for freight. 3. A long platform car, either having no sides or with very low sides, used on railroads. Origin: It, dim. Of gonda a gondola; cf. LL. Gandeia a kind of boat, Gr. A drinking vessel; said to be a Persian word; cf. F. Gondole gondola, cup. Source: Websters Dictionary (01 Mar 1998) |
