Which lexemes are more frequent: verbs or nouns? NONE. Below is a proof by example. :-)
There are many lexical frequency analyzers for most world languages - both amateurish and professional - including Polish. I just picked one from PWN, korpus.pwn.pl/stslow_en.php
Word frequency in the demonstration corpus - top 200Following is a lexeme frequency list for the demonstration version of the corpus sampler. The frequency of the lexemes was calculated after summing up the frequency of all forms, and in the case of homonymic forms - with reference to the proportions of their occurrence in Słownik frekwencyjny polszczyzny współczesnej [A Frequency Dictionary of Contemporary Polish].
Shown here are only the first two dozen or so lexemes, to give you some idea how it works. This is a simplified presentation. Each triad is made of: (rank frequency lexeme). Original list shows both combined inflected and individual inflected forms. Here are shown just the combined forms. The first noun on the list is "rok" (including "r.") - appearing not until the 21st rank. "Być" (3) and "mieć"(16) both precede it.
The list of most frequent verbs is quite interesting since most people would agree that they are the most important verbs: być, mieć, móc, wiedzieć, mówić, chcieć, musieć, powiedzieć, zostać.
The similar list of nouns looks to me almost random: rok, czas, człowiek, praca, pan, przykład, dzień. I could probably go away without half of them here. :-)
In conclusion - by being professionally skewed "functional programmer" (as opposed to "object oriented programmer") - I vote for the actions, the functions, the VERBS. :-)
