Classificatory essay

Finally, include a thesis sentence (usually at the end of the introduction) that briefly identifies the main types or approaches that you're about to examine. Here's an example of a short but effective introductory paragraph to a classification essay:

Classification is a method of developing an essay by arranging people, objects, or ideas with shared characteristics into particular classes or groups.

To differentiate descriptive and classifica­tory system it can be said that in the descriptive system a single special term is applied to each relation, whereas in the classificatory system there is a combination of primary terms. Meyer Fortes has given an analysis of the legacy of Lewis Henry Morgan in his work Kinship and the Social Order.

The descriptive system is defined as the reverse of the classifica­tory system. In this system each relationship falls in the recognized relationship. The relations are not classified but are addressed only as their description is given.
