History
Teaspoon is a European invention. Small spoons were common in Europe since at least the 13th century, the special spoons were introduced almost simultaneously with the tea and coffee (Pettigrew points to use in the mid-17th century). Originally the teaspoons were exotic items, precious and small, resembling the

s of the later times. Also used for coffee, these spoons were usually made of
gilt silver, and were available with a variety of handle shapes: plain, twisted, decorated with knobs, also known as ''knops'', hence the ''knop-top'' name for such spoons. Widespread use and modern size date back to the

", was a part of the
tea set in the 18th century. At that time, the spoons were playing important role in the tea drinking etiquette: a spoon laid "across" the teacup indicated that the guest did not need any more tea, otherwise, the hostess was obligated to offer a fresh cup of tea, and it was considered impolite to refuse the offering. Pettigrew reports that sometimes the spoons were numbered to make it easier to match the cups with the guests after a refill.

The household teaspoons provide very bad approximations of any unit of measure. In a small-scale research, Falagas et al. found out that the volume of liquids inside different tablespoons varies almost three times, between 2.5 and 7.3 ml (the average value was 4.4 ml).

Dry ingredients
For dry ingredients (e.g., salt, flour, spices), if a recipe calls for a ''level'' teaspoon, it refers to an approximately leveled filling of the spoon, producing the same volume as for liquids. A ''rounded'' teaspoon is a larger but less precise measure, produced by heaping the ingredient as high as possible without leveling the ingredient off. A ''heaping'' (North American English) or ''heaped'' (UK English) teaspoon is an even larger inexact measure consisting of the amount obtained by scooping the dry ingredient up without leveling it off.

, this quantity can vary considerably.
Apothecary
As an unofficial but once widely used unit of apothecaries' measure, the teaspoon is equal to 1 fluid dram (or drachm) and thus of a tablespoon or of a fluid ounce. The apothecaries' teaspoon was formally known by the Latin ''cochleare minus'' (''cochl. min.'') to distinguish it from the tablespoon or ''cochleare majus'' (''cochl. maj.'').
When tea-drinking was first introduced to England circa 1660, tea was rare and expensive, as a consequence of which teacups and teaspoons were smaller than today. This situation persisted until 1784, when the Commutation Act reduced the tax on tea from 119% to 12.5%.[Tea.co.uk. (2020). UK Tea & Infusions Association Illicit Tea Trades. nlineAvailable at: https://www.tea.co.uk/tea-smuggling ccessed 1 February 2020] As the price of tea declined, the size of teacups and teaspoons increased. By the 1850s, the teaspoon as a unit of culinary measure had increased to of a tablespoon, but the apothecary unit of measure remained the same. Nevertheless, the teaspoon, usually under its Latin name, continued to be used in apothecaries' measures for several more decades, with the original definition of one fluid dram.
