The idea of a conceptual metaphor came from a book by George Lakoff and Mark Johnson in 1980: "Metaphors we live by".
A convention is to write conceptual metaphors in small capital letters, e.g. , with the target domain (idea being referred to) first, here "money," and the source domain (terms used to refer to it) second.
There are many more, enough to prove the importance of the metaphor in our lives.

Crust is a piece of bread where the edge where it is harder and darker.

Comedy
Comedy (from ), in modern times, is entertainment with generally funny content. It is able to make people laugh. This definition was used for theatre plays, and was first used in Ancient Greece. Aristotle defined this as “Comedy is, as an imitation of characters of a lower type- not, however, in the full sense of the word bad, the ludicrous being merely a subdivision of the ugly. It consists in some defect or ugliness which is not painful or destructive. To take an obvious example, the comic mask is ugly and distorted, but does not imply pain.” To him, the lampooners became writers of Comedy and the truly artistic ones became writers of Tragedy.
Comedy is also a media genre that is for television shows or movies that are either funny or silly. People who are known for acting in comedies are termed as comedians or comedic actors.
The ancient Greeks had comedies, which were presented in competitions at the festival of Dionysia.
One of the best-known comedy authors of the time was Aristophanes (about 446386 BC). One of his works, "The Clouds" was performed 425 BC. The work did not survive completely, but a later version did survive. It is a satire against Socrates, and pictures the great philosopher as a swaggering con artist. Some of the accusations were re-used at Socrates' trial, twenty years later.
Typical for satire are that the author criticizes society, and living people.
Another type of Ancient Greek theatre was the satyr play. This was mock drunkenness, brazen sexuality (including phallic props), pranks, sight gags, and general merriment. The modern equivalent would be knock-about comedy.
Humour, or 'New Comedy' is not about criticizing people or ideas, but rather about showing characters in funny situations. The most important Greek playwright of this type was probably Menander. The best known Roman comedy writer was Plautus. He often used Greek comedies for his plays.
Many comedy plays were written in the 1500s by the British writer William Shakespeare.
Shakespeare's comedy plays include:" All’s Well That Ends Well, The Comedy of Errors, A Midsummer Nights Dream", and "Twelfth Night". In Shakespeare's day a comedy did not mean a play that would make people laugh or that had a lot of jokes. Instead it was a play in which all the problems work out all right in the end. This was unlike a tragedy, where the problems do not work out, usually resulting in someone's death.
The two masks, one was smiling, the other crying, often associated with theatre represent comedy and tragedy.
There are different types of comedy. One type of comedy is called "slap stick comedy." In "slap stick comedy," people do silly things such as tripping, falling over or embarrassing themselves just to make people laugh. Slap stick comedy can be used in comedy movies or comedy television shows.
Slap stick comedy was used a lot in silent (no sound) movies from the 1920s. A comedian who acted in the silent movies who used a lot of slapstick comedy was Charlie Chaplin. In the 1950s and 1960s, comedian Jerry Lewis also used silly slap stick comedy in his comedy movies.
A comedy is a very popular type of movie. Some comedy movies have "slapstick comedy," in which people just do silly things such as tripping, falling over or embarrassing themselves just to make people laugh. Other comedy movies show funny stories or situations in which people are behaving in a silly manner. Some comedies make the audience laugh by showing strange or unusual images or situations that do not make sense.
A parody or spoof movie imitates or exaggerates another person or movie to make them seem silly, dumb, or just plain out of it.
Some types of comedy movies mix comedy with other types of movies.
Comedy shows are very popular on television. Comedy shows on television are often called "sitcoms." The word "sitcom" is a shortened way of saying "situational comedy." Television situational comedies usually show characters who do silly or funny things which make the audience laugh.
Comet
A comet is a ball of mostly ice that moves around in outer space. Comets are often described as "dirty snowballs". They are very different from asteroids. The orbital inclinations of comets are usually high and not near the ecliptic where most solar system objects are found. Most of them are long-period comets and come from the Kuiper belt. That is very far away from the Sun, but some of them also come near enough to Earth for us to see at night.
They have long "tails", because the Sun melts the ice. A comet's tail does not trail behind it, but points directly away from the Sun, because it is blown by the solar wind.
The hard centre of the comet is the "nucleus". It is one of the blackest things (lowest albedo) in the solar system. When light shone on the nucleus of Halley's Comet, the comet reflected only 4% of the light back to us.
"Periodic" comets visit again and again. "Non-periodic" or "single-apparition" comets visit only once.
Comets sometimes break up, as Comet Biela did in the 19th century. Comet Shoemaker-Levy 9 broke up, and the pieces hit Jupiter in 1994. Some comets orbit (go around) together in groups. Astronomers think these comets are broken pieces that used to be one object.
For thousands of years, people feared comets. They did not know what they were, or where they came from. Some thought that they were fireballs sent from demons or gods to destroy the earth. They said that each time a comet appeared, it would bring bad luck with it. Whenever a comet appeared, a king would die. For example, the Bayeux Tapestry shows the return of Halley's Comet and the death of a king. Comets were also known to end wars and thought to bring famine. During the Renaissance, astronomers started to look at comets with less superstition and to base their science on observations. Tycho Brahe reasoned that comets did not come from the earth, and his measurements and calculations showed that comets must be six times farther than the earth is from the moon.
Edmond Halley reasoned that some comets are periodic, that is, they appear again after a certain number of years, and again and again. This led to the first prediction of a comet's return, Halley's Comet, named after him.
Isaac Newton also studied comets. He realised that comets make U-turns around the sun. He asked his friend Edmond Halley to publish this in his book "Philosophiae Naturalis Principia Mathematica". Before Newton said this, people believed that comets go in to the sun, then another comes out from behind the sun.
In later years some astronomers thought comets were spit out by planets, especially Jupiter.
All this new information and research gave people confidence, but some still thought that comets were messengers from the gods. One 18th century vision said that comets were the places that hell was, where souls would ride, being burned up by the heat of the sun and frozen by the cold of space.
In modern times space probes have visited comets to learn more about them.
Cytology
Cytology is the study of the cells, especially their appearance and structure. Cells are the small parts that make up all living things, and their effects on each other and their environment.
