In A Greek–English Lexicon, it is defined as a "name of a dish compounded of all kinds of dainties, fish, flesh, fowl, and sauces".

It is the longest Greek word, containing 171 letters and 78 syllables. The transliteration has 183 Latin characters and is the longest word ever to appear in literature, according to the Guinness World Records (1990).
