Yes. Google on <"zipf's law"> and look at the sites listed
on the first page of returns. You will find that I am
right, and that there is a very considerable literature on
the subject, as well as a number of generalizations (e.g.,
the Zipf-Mandelbrot law).

He is best known for Zipf's Law, which is as I stated it
above.

Yes, I've read that. It refers to what I mentioned and you
snipped: 'his observation that "the length of a word tends
to bear an inverse relationship to its relative frequency",
which I suppose is what you have in mind here'. He never
suggested any specific mathematical relationship between
word-length and frequency, and a fortiori proposed no law
relating the two: 'tends to bear an inverse relationship to'
is far to vague to be called a law even if the term 'Zipf's
Law' weren't already in general use for something else.

No, it doesn't. It means that unlike you, he knows what
Zipf's Law is.

Don't be ridiculous. 'The length of a word tends to bear an
inverse relationship to its relative frequency' doesn't
require anything of any specific word; it's a vague,
qualitative description of a lexicon.
