Tallow is a type of animal FAT that has been used for centuries as a source of fuel and lubricant. It is made from the rendered FAT of sheep or cattle, and is also used in the production of candles and soaps. The term 'tallow' can be broken down into three parts: SUET (4 letters), FAT (3 letters), and CANDLE (6 letters). SUET is the raw, hard FAT found around the kidneys and loins of animals, while FAT is a general term for any type of fatty tissue. CANDLE is a product made from tallow that is used for lighting and decoration.
