A dais is simply a platform (typically raised) on which something or someone is placed so as to be easily viewed. Interestingly, the term is applied to platforms ranging from small wedding cake dais on which the bride and groom statuette is placed to a large platform on which persons are found who will be addressing a large audience. Landscaping makes use of a dais on which a statute or fountain or some such other decorative item is placed. It is also a family name and a type of tree. df, Calgary, AB.
