Eternity refers specifically to time without end, or existence that never stops, while infinity is a broader mathematical and philosophical concept referring to something without any limit, not necessarily tied to time. Eternity is essentially infinity applied to the dimension of time.

"Eternity" is often used loosely to describe an amount of time that feels endlessly long, even though it is not literally infinite, as in "we waited an eternity for the results." This figurative use exaggerates duration for emphasis.

"For eternity" means forever, without any end, and is often used in emotional or poetic contexts such as vows or memorials to express a permanent, unending commitment or state.
