<P> A tablespoon is a large spoon used for serving or eating . In many English - speaking regions, the term now refers to a large spoon used for serving, however, in some regions, including parts of Canada, it is the largest type of spoon used for eating . By extension, the term is used as a measure of volume in cooking . In this capacity, it is most commonly abbreviated tbsp or T, and occasionally referred to as a tablespoonful to distinguish it from the utensil . The unit of measurement varies by region: a United States tablespoon is approximately 14.8 ml (0.50 US fl oz), a United Kingdom and Canadian tablespoon is exactly 15 ml (0.51 US fl oz), and an Australian tablespoon is 20 ml (0.68 US fl oz). The capacity of the utensil (as opposed to the measurement) is not defined by law or custom and bears no particular relation to the measurement . </P> <P> Before about 1700, it was customary for Europeans to bring their own spoons to the table . Spoons were carried as personal property in much the same way as people today carry wallets, key rings, etc . From about 1700 the place setting became popular, and with it the "table - spoon", "table - fork" and "table - knife". Around the same time the tea - spoon and dessert - spoon first appeared, and the table - spoon was reserved for eating soup . The 18th century witnessed a proliferation of different sorts of spoons, including the mustard - spoon, salt - spoon, coffee - spoon, and soup - spoon . In the late 19th century UK, the dessert - spoon and soup - spoon began to displace the table - spoon as the primary implement for eating from a bowl, at which point the name "table - spoon" took on a secondary meaning as a much larger serving spoon . At the time the first edition of the Oxford English Dictionary was published in 1928, "tablespoon" (which by then was no longer hyphenated) still had two definitions in the UK: the original definition (eating spoon) and the new definition (serving spoon). </P>
