There are many solutions, and using a word list and a simple program a complete solution is not hard to find; the problem was intended (unlike most on this site) to be solved off the top of your head, without aid of a computer.
Here are the words I came up with and expected most people to find (or variations thereof):
MILLILITER
LIGHTHOUSE
LIGHTHEARTED
ICHTHYOSAUR
DIPHTHONG
KNIGHTHOOD
EIGHTH
PIQUANT
ANTIQUATED
RELIQUARY
DRAWBACK
JAWBONE
JAWBREAKER
LAWBREAKER
STRAWBERRY
But of course, there are more words that can be found:
1. I believe that milliliter is the unique word (sans its plural form) with the letter sequence illili in it.
2. There are many obscure words for hth. I will just list the roots: autochthon, chthonian, diphtheria, diphthong, eighth, exophthalmus, ichthyology, ichthyosaur, knighthood, lighthearted, monophthong, naphthol, nighthawk, ophthalmia, ophthalmology, phthalein, phthiriasis, phthisis, triphthong.
3. There are fewer words for iqua: antiquate, biquadratic, liquate, piquant, reliquary, semiquaver (and variants of those words).
4. And finally, for awb, we have: bawbee, drawback, drawbar, drawbridge, jawbone, jawbreaker, lawbreaker, rawboned, sawbuck, strawberry, strawboard. |
