The word metaphor comes from a Greek word meaning ‘transfer’. Metaphors compare two things or ideas: a quality or feature of one thing is transferred to another thing. Some common metaphors are
• the leg of the table: The leg supports our body. So the object that supports a table is described as a leg.
• the heart of the city: The heart is an important organ in the centre of our body. So this word is used to describe the central area of a city.
