Macmillan Dictionary offers unique treatment of metaphor, showing how many ordinary familiar words and phrases have metaphorical meanings. The dictionary has over 60 special features on metaphor, called Metaphor Boxes, to help you reach a deeper understanding.
This article and the Metaphor Boxes in Macmillan Dictionary were written by Dr Rosamund Moon, an expert in the field of metaphor.
Metaphor is very common in English and other languages. People often think of it as being a typical feature of poetry and literature. But, in fact, many familiar words and phrases have metaphorical meanings, although we do not usually realize this when we use them.
Look at these three sentences:
In all these sentences, the word in bold type is not used in its basic or literal meaning – it is used in a metaphorical way.
A metaphor is a type of comparison: when you use a word or phrase metaphorically, you are using a meaning that has developed from the literal meaning and has some of the same features. For example, if you say someone 'flies past' on a bicycle or in a car, they are not really flying through the air, but the speed of their movement reminds you of a plane or a bird. This is a normal part of the way word meanings develop, and when a word has several meanings, some of those meanings are usually metaphorical.
Every metaphorical word or phrase contains a 'key idea'. This is the connection or similarity between the literal meaning and the metaphorical meaning.
Sometimes the same key idea is expressed in several different words and phrases.
For example, when we talk about illness, we often use words and phrases whose literal meanings are to do with fighting or war:
The key idea in this case is that trying to recover from an illness is like fighting a war, and many of the words and phrases that we use for talking about illness express this idea. Once we understand this key metaphorical idea, it is easier to understand (and remember) words and phrases used for talking about illness. This is why metaphor is so important.
Metaphor is so common that it is sometimes almost impossible to talk about particular topics in English without using words that are metaphorical. For example, many common English words referring to responsibilities are metaphorical. In this case, the key idea is that having a responsibility is like carrying a load: the bigger the responsibility, the heavier the load:
Even though we may not realize that we are speaking metaphorically, the basic metaphorical idea has influenced the way that a particular concept is expressed in English, and this affects the way English speakers think about it. Metaphors that provide us with ways of thinking and ways of talking about things are called conceptual metaphors, and they are the subject of an important book, Metaphors We Live By, by George Lakoff and Mark Johnson. Many other people have written about metaphor, but Lakoff and Johnson introduced the ideas that have influenced the Metaphor Boxes in Macmillan Dictionary.
Idioms often contain metaphorical ideas: for example, expressions like spill the beans and give someone a hand are metaphorical. Similes are very like metaphors. The difference is that they include words such as like or as, which make it clear that two things are being compared. For example, that man is an animal is a metaphor, but he behaves like an animal is a simile. We have included idioms and similes in the Metaphor Boxes if they show the same key idea as other words in the group.
The Metaphor Boxes can be found at the main dictionary entry that relates to the topic of each metaphor. So the Metaphor Box listing metaphors about illnesses is at the entry for illness (not at the entry for fight, which is the key idea). These boxes show many of the main words and phrases that express the key idea. But you may be able to think of other ones that contain the same idea.
Sometimes a topic has two different groups of metaphors, each showing a different key idea. For example, the Metaphor Box at relationship shows that we think of relationships in two different metaphorical ways:
1: like a physical connection:
2: like temperature or the weather:
