and Folk Taxonomy. They found a way to determine, with a high degree of reliability, the major outlines of the named taxonomic structure of the plant world for Tzeltal speakers. Tzeltal is one of the Mayan languages spoken in Mexico, in which most linguists distinguish six different regional dialects. In this study, they found many cultural and meaningful categories related by inclusion that are not conventionally labeled. In their language, the different plants in each category all have a common word structure that puts them apart from all of the other plants. They found that you cannot trace the words back to a single source where all plant names are included. In most languages, they have a "unique beginner" that you can trace the names back to. What Berlin and his colleagues found is that plants and animals are thought of as two separate unnamed classes. In plant taxonomy, the highest level is not a "unique beginner" but is instead represented by four major lexemes or units. These four levels are trees, vines, grasses, and herbs. There are more minor classes that include cacti, agaves, bamboos, etc. There are also very few midlevel plant categories. All of the Tzeltal specific taxa (those that which include no other members) fall into the different major and minor sublevels in their taxonomy. But, it is odd to note that the midlevel category hihte, or "oak", contains the plants sikyok and cikinib which neither share the same linguistic structure with their "parent plant." To test the hypothesis they first went through the community, observed, and recorded information from their informants comments of the plants in their natural habitats. When they went out into the field to collect data, they noticed that some of 10,000 specimens that were located in the same named contrast set were closely related than others. They take into account the uses of the certain plants including food, herbs, firewood and so on. A second method that was used helped with searching for possible subgroupings within contrast sets of large numbers was to determine the extent to which informants subdivided lists of plant names. To do this, they wrote the names of different names of plants and animals on slips of papers and then gave them to their informants. After doing this, the informants then put the slips of papers into groups that were most like each other. The results showed
