Expert writing Tips
Best practice
Use "eternity" to convey the concept of timelessness or an infinitely long period. Ensure the context aligns with the sense of unending duration, whether in a literal or figurative sense.
Common error
Avoid using "eternity" when referring to merely extended periods. "Eternity" implies infinity, while a long duration is still finite, however extended it can be.
