O.E. æfre, no cognates in any other Gmc. language; perhaps a contraction of a in feore, lit. "ever in life" (the expression a to fore is common in O.E. writings). First element is almost certainly related to O.E. a "always, ever," from P.Gmc. *aiwo, from PIE *aiw- "vital force, life, long life, eternity." (see eon).
Really; truly; certainly •Used postpositively for emphasis: Boy, has it ever!/ Clinton's generation has already had its chance to make its tastes the country's tastes. Has it ever/ Did we win? Did we ever!
