Use of "that" for enumerate concepts
Hi everyone! I'm finding difficult to differentiate if the parragraph of a book I'm reading (Foundations of Statistical Natural Language Processing, by Minning and Schütze) is refering to just one concept, or to actually two. It says the next:
"Other laws of Zipf’s include that there is an inverse relationship between the frequency of words and their length, that the greater the frequency of a word or morpheme, the greater the number of different permutations (roughly, compounds andmorphologically complex forms) it will be used in".
I can't decide if there is just one concept, whit is related to the "relationship between frecuency of words and their length"; or in fact there is another concept when it says "that the greater the frequency of a word or morpheme, the greater the number of different permutations".
I think my problem is related to the use of "that", as I think it could be used to enumerate things (but not sure).
I'd trully appreciate your help!
