A top It is an element that allows to close some type of container or container . For example: "I can't find the lid of the jam jar ... can you help me find it?", "Be careful when moving toys: that box has no lid", "The bottle cap prevents gas from being lost".

The covers fulfill various functions. They can be used so that what is stored in a container do not fall or don't get lost They also help keep it clean , preventing dust or dirt from entering the container.
Cap, on the other hand, is the name that receives the cover of a book . Each bound work, in this way, has two covers: the cover (the front cover) and the so-called back cover (the cover that appears on the back of the book): "The new book of the French novelist generated a great controversy as it shows a decapitated man on the cover", “The cover of my poems was illustrated by a Chilean artist”, “I like to choose the books I buy according to the covers”.
The cover idea also appears in the field of gastronomy . In Spain , the reduced portion of various foods They are offered as a snack. The activity that consists of visiting one or more restaurants to eat tapas is known as “Go for tapas” or "Cover".
It is worth mentioning that this habit of going for tapas is very common in Spain, so much so that in several of its regions it can be used instead of going out to eat more traditional, normal in other countries, which consists of going to a particular establishment for lunch or have dinner dishes complete and abundant. As usual, tapas means stopping in more than one place , that is, it is not a well-defined exit but rather a relatively spontaneous activity, open to last-minute changes.
But the Spanish cover is not only enjoyed by the common citizen as part of their leisure trips, but has become part of the country's identity and is even offered at high-level receptions. To cite a very graphic example of the scope that has come to have this habit During a visit to Spain by Raísa Maksímovna Gorbachova, wife of the former president of the Soviet Union Mikhail Gorbachev, the mayor of Madrid and Queen Sofia invited her to a banquet in which the cover was one of the main elements.
Always in the same context of gastronomy, it is known as miniature kitchen precisely to the culinary branch that specializes in dishes such as the tapas, the montaditos, the skewers, the banderillas and the appetizers , among others, but facing them as if they were part of the high kitchen . The well-known chef Ferran Adrià, highly acclaimed in his country, has managed to fuse the concept of tapas with the world of haute cuisine, and uses it for the preparation of his entrees.
With respect to the etymology of the word "tapa" in this case, there are those who argue that this particular use is linked to the custom of covering the glasses with slices of bread or cold cuts to prevent insects that get inside the dishes are usually around food , such as flies, and also to protect beverages from dust particles that float in the environment.
The action of "going for tapas" also receives other names, depending on the geographical location: in Aragón and Navarra there is talk of "Alifara", while in the Basque Country they call it "poteo".
At basketball or basketball , a lid is a blocking which a player performs to prevent the opponent from scoring. The term, depending on the country, can be known as plug or Cap .
