Imagine stretching a rubber band and watching it snap back to its original shape. This property is what we call elasticity, our focus word for today’s IELTS vocabulary lesson.
Word type: Elasticity is a noun.
Meaning: Elasticity refers to the ability of an object or material to return to its original shape after being stretched or compressed.
In a broader sense, particularly in economics, it describes the degree to which a variable changes in response to another variable.
For instance, price elasticity of demand measures how much the demand for a product changes when its price increases or decreases.
Word history: The term elasticity comes from the Greek word elastos, meaning ductile or flexible. It entered the English language in the early seventeenth century, initially describing physical properties.
Its use in economics was introduced in the late nineteenth century by Alfred Marshall.
Antonyms: Some antonyms for elasticity include rigidity, inflexibility, and inelasticity.
These terms describe a lack of responsiveness or ability to change.
Synonyms: Synonyms for elasticity include flexibility, resilience, malleability, and adaptability.
These words all convey the idea of being able to change and return to an original state.
Examples use in sentences:

Economists closely monitor the price elasticity of demand for various goods to predict consumer behavior in response to market fluctuations.
