sempiternal

adj

Etymology: From Old French sempiternel, from Medieval Latin sempiternālis, from Latin sempiternus, a contraction of semperæternus, from semper (“always”) + æternus (“eternal”).

1. Everlasting, eternal.

   “The one thing which we seek with insatiable desire is to forget ourselves, to be surprised out of our propriety, to lose our sempiternal memory, and to do something without knowing how or why; in short, to draw a new circle. Nothing great was ever achieved without enthusiasm.”

   “Why not sempiternal / Thou and I? Our vernal / Brightness keeping, / Time outleaping: / Passed the hodiernal!”

2. Having infinite temporal duration, rather than outside time and thus lacking temporal duration altogether; everlasting.
