Another new verse form: the equiliteral tercet. Like its geometrical model, the equilateral triangle, it’s composed of three equal parts: three lines of three words, each with three letters. It need not rhyme, but these three examples do:
Old men say
Now it’s day
Cut the hay
Sty for pig
Fly for fig
Tie for gig
Did our cow
Get ill now
Why and how
