Lewis Carroll Gives an Example of Human Perversity

"[Let] me take this opportunity of answering a question that has often been asked me, how to pronounce "slithy toves." The "i" in "slithy" is long, as in "writhe"; and "toves" is pronounced so as to rhyme with "groves." Again, the first "o" in "borogoves" is pronounced like the "o" in "borrow." I have heard people try to give it the sound of the "o" in "worry." Such is Human Perversity."
