I know I took a vow of silence about the previous discussion of the letter "o" . . . but I now have the book "Facts in Jingles" by Miss Winifred Sackville Stoner, Jr., and can't resist posting this poem:
THE GLORIOUS O
How plain the sound of common tea,
And plainer still LE THE,
But TEO, lovely TEO
All linguists love to say!
How common sounds—cup coffee.
Le café floats in air
With Kafo, Bona Kafo
No drink can quite compare.
How vulgar the word butter
Le beurre is just as bad,
But the good word butero
Will always make us glad.
We Esperantists modest are,
