Sense: abbreviation/1
Teaspoon and teaspoonful both refer to the same standard cooking measure, but teaspoonful emphasises the quantity that fills a spoon (e.g. 'a teaspoonful of medicine'). Tsp is simply the abbreviated form used in written recipes and ingredient lists. The most common confusion is with tbsp (tablespoon): a tablespoon holds roughly 15 ml, while a teaspoon holds about 5 ml. In recipes, mistaking one for the other changes the dish significantly. When reading a recipe aloud, say 'teaspoon' rather than 'tsp'; write 'tsp' in shopping lists or notes.

Etymology
Tsp is a shortened form of the word teaspoon, which was formed by combining tea and spoon in the 1600s, when tea drinking became popular in Europe and small spoons were used for measuring and stirring the leaves.
