OK, I'm pretty sure we're on the right track with "beau" being the def. Dunno what the other one(s) are though
Can "uncertain" be a non-anagram indicator of some sort? "Certain" could mean "some but not all," so it's a stretch, but "uncertain" could mean "only certain letters in 'un'," which would be U or N
Another thought I had: maybe it's "uncertain about" instead of just "uncertain"
But hard to see how that would be helpful
I'm gonna throw out another possible word for y'all to dissect: CAVALIER, def "beau," and contains I = "current" which is "about" a word, and ER = "uncertain"(?) or possibly "queen" as in "Elizabeth Regina"
Dunno how to get CAVAL from the other parts of the wordplay though
@bobble I don't think "uncertain" is cluing an anagram here - the word would then have to contain either an anagram of QUEEN or of ABOUT most likely, and none of the possible solutions I've come across has all those letters in them
So it's either some other tricky kind of indicator, or it's straight cluing a word
What type of convex nonagon is required to tesselate a plane with equilateral triangles and nonagons? All sides of the nonagons are equal.
NOTE: Partial tessellation of a plane should accompany your answer.
