  • I am glad she wept so much, because no heart bursts (be the occasion for the sorrow what it will) which has that kindly relief. Hence I hardly ever am moved at the sight of these pellucid fugitives in a fine woman.

  • As ironic as it may be, using the word "pellucid" in a sentence makes it anything but that.

  • This sounds like it could be the name of a Turkish dynasty.

  • I think it is a lovely word, with light – lux – shining through (per > pel) from its core, with the tintinnabulation of the initial pell- sound. There is nothing whatsoever opaque about this word.

  • Yes, the word, perlucid, were there one, would never work. Thank God for ancestors who used prefixes and suffixes mellifluously.

  • I imagine it may have been the inspiration for Pella windows. Signed, Too Lazy to Read the Company Site to Find Out.

  • Funny, I always assumed that. But then you had to go and pique my curiosity and post the Pella website. Here's what I found:

    1925

    Pete and Lucille Kuyper invest in a small Des Moines, Iowa company that manufactures Rolscreen® window screens

    1926

    The Kuypers move the company to their hometown of Pella, Iowa

    So now I'm wondering: Was Pella, IA, named after "pellucid"? ;-)

  • Wasn't Pella the capital of Philip of Macedon and his son Alex?
