Synonym Chooser
Some common synonyms of energy are force, might, power, and strength. While all these words mean "the ability to exert effort," energy applies to power expended or capable of being transformed into work.
a worker with boundless energy
While in some cases nearly identical to energy, force implies the actual effective exercise of power.
used enough force to push the door open
While the synonyms might and energy are close in meaning, might implies great or overwhelming power or strength.
the belief that might makes right
In some situations, the words power and energy are roughly equivalent. However, power may imply latent or exerted physical, mental, or spiritual ability to act or be acted upon.
the awesome power of flowing water
The synonyms strength and energy are sometimes interchangeable, but strength applies to the quality or property of a person or thing that makes possible the exertion of force or the withstanding of strain, pressure, or attack.
