What, you may ask, is the plural form of the word "Rendezvous?" It is actually the same as the singular form--no extra "s" or apostrophe necessary. The distinction is in the pronunciation. When using the singular form, you do not pronounce the "s" at the end; it is silent. To pluralize it, you simply pronounce the "s." Singular: Rendezvous ( rän-di- vü) Plural: Rendezvous ( rän-di- vüz )
