Ms. Silver had been talking about different habitats. While she talked, she pointed to posters on the bulletin board labeled THE OCEAN and THE RAIN FOREST and THE PRAIRIE. Then she talked about the different names for the specific places animals live, their homes. She mentioned nests and webs and caves and dens and burrows.
I read the above paragraph on Page41 in the book the Year of Billy Miller. I found out that the writer used more than one 'and' in his writing to connect the items in a list. As far as I know is that when you are linking more than two items, you usually only put and in front of the last one.
What is the purpose of the author using and to connect all items? Is it kind of writting skill to emphasize the sentence? I have checked the similar question, but it seems to me that the two questions are a little different.
