  In his pioneering research, G. K. Zipf formulated a couple of statistical
laws on the relationship between the frequency of a word with its number of
meanings: the law of meaning distribution, relating the frequency of a word and
its frequency rank, and the meaning-frequency law, relating the frequency of a
word with its number of meanings. Although these laws were formulated more than
half a century ago, they have been only investigated in a few languages. Here
we present the first study of these laws in Catalan.
  We verify these laws in Catalan via the relationship among their exponents
and that of the rank-frequency law. We present a new protocol for the analysis
of these Zipfian laws that can be extended to other languages. We report the
first evidence of two marked regimes for these laws in written language and
speech, paralleling the two regimes in Zipf's rank-frequency law in large
multi-author corpora discovered in early 2000s. Finally, the implications of
these two regimes will be discussed.
