perpetualvsephemeral
Perpetual means never ending — continuing without interruption, on and on. Ephemeral means the opposite: lasting only a very short time, here and then gone. One never stops; the other is over almost before it begins.
Two wheels geared into each other turn without stopping, one against the other, a marble riding the rim past the same point again and again while a pendulum keeps its patient time below — heading nowhere, just coming round and round.
/pərˈpetʃuəl//pəˈpetʃuəl/·adjectiveGrain by grain a mandala is built, whole for only the last moment, before a gust crosses it left to right and undoes the lot in a second and a half — a faint ghost of the design hanging in the air, then gone.
/ɪˈfemərəl//ɪˈfemərəl/·adjectiveBoth words measure how long something lasts, and they sit at the far ends of the scale. Perpetual comes from the Latin perpetuus, 'continuous': a perpetual motion machine would never stop, perpetual snows never melt. Ephemeral comes from the Greek ephēmeros, 'lasting a day' — once used for creatures that lived no longer than a single sunrise to sunset. One word names what refuses to end; the other names what is gone in a moment, and is often admired precisely because it is.
What each means
perpetual
Perpetual means going on forever, or near enough — from the Latin perpetuus, 'continuous'. A perpetual motion machine would never stop; perpetual snows never melt; a perpetual complainer never lets up. The word can describe the genuinely endless or, with a sigh, the merely relentless. Unlike what is ephemeral and gone in a moment, the perpetual refuses to end; it is the state that simply continues to persist, cycle after cycle, with no final beat.
ephemeral
Ephemeral describes what is here and then gone — beauty, fame, fashions, mayflies. From the Greek ephēmeros, 'lasting a day', it originally described creatures that lived no longer than a single sunrise-to-sunset. Today it carries a wistful, almost poetic tone: to call something ephemeral is not just to say it is brief, but to notice its brevity, the way cherry blossoms are admired precisely because they fall so soon.

How to remember the difference
Picture the timer. Perpetual is the geared wheels turning with no build and no finish, the marble passing the same point forever — watch as long as you like and it only ever does what it's already doing. Ephemeral is the sand mandala complete for a single moment before a gust erases it, the empty stage afterward as much a part of the piece as the pattern was. One refuses to end; the other is over almost before it starts. If it goes on without stopping, it's perpetual; if it's gone in a moment, it's ephemeral.

They are listed as antonyms of each other. Note the related verb 'perpetuate' (to keep something going, as in 'perpetuate inequality'), which differs from the adjective 'perpetual'; and ephemeral carries a wistful tone — it doesn't just mean brief, it notices the brevity.
