that they had no trouble placing them in the different categories of "plants" and "animals." This also showed that though they did not have a word for it they did know of the existence of "plants." After this, they broke down the taxonomy even further by giving them different "plant" names and asking them the same question, as before they had no problem labeling each plant into the different groups or categories. After they established that they understood the existence of subgroupings, they used three different procedures to find out how they define the features of certain plants. The first procedure was called the triads test in which the informants chose which item out of a group of three was the most different. The results indicated how they group things together based upon similarity. The second procedure involved constructing folk keys. The keys are used to help distinguish the different plants from the other based upon the traits. They then used these to get a better understanding of why certain plants were put in certain places in their taxonomy. First they would give the informants the names of plants that they had earlier grouped together (when the researchers gave them the slips of papers with names on them), then they were asked to create a key that would help distinguish each plant from each other. In doing this, the informants showed how they make their divisions between plants and decide which group to put them in. Finally, they conducted a study consisting of paired comparisons of all the items in a particular set of plant names. The informants were asked to compare all the logical pairs in different sets and make logical comparisons and differences amongst them. Characteristics such as stem growth, size and shape of the stem and leaves, and fruit size and shape were all utilized when making the comparisons. This showed Berlin, Breedlove, and Raven what the "definitions" were for a set of terms and they were then able to bring together the like terms that were the most similar according to the informant in question. This study showed what the Tzeltal people deem as the most important features to them when they decide to on certain plants to take care of and plant for their very immediate survival. This results from this study shows that things that do not have names for the Tzeltal speakers still
