"A trivet /ˈtrɪvɪt/ is an object placed between a serving dish or bowl, and a dining table, usually to protect the table from heat damage. Whilst tri- means three, and -vet comes from -ped, meaning ´foot´ / ´feet´, trivets often have four ´feet´, and some trivets, including many wooden trivets, have no ´feet´ at all.
Trivet also refers to a tripod used to elevate pots from the coals of an open fire (the word trivet itself ultimately comes from Latin tripes meaning "tripod"). Metal trivets are often tripod-like structures with three legs to support the trivet horizontally to hold the dish or pot above the table surface. These are often included with modern non-electric pressure cookers. A trivet may often contain a receptacle for a candle that can be lit to keep food warm." - (en.wikipedia.org 27.08.2021)
