Dear Faldage:

Rollercoaster just sounds so dadburned SLOW to me--more like a lazy afternoon at the beach, waves slowly tumblin' in, lazy waves as drowsy and dreamy as waves can sometimes be--boats in the distance barely wafting along.

That's what the word rollercoaster sounds like to me.

Some words just don't evoke what they are. Like tsuwm's philtre or philter, I've forgotten which, for the dip above your lips below the nose. That is a most horrible, nasty, clinical word for something so gently lying there.

Best regards,
