A Venn diagram is used to compare two related words or concepts by writing one in each circle, with similarities written in the overlapping center section and differences outside in the non-overlapping sections. For example, a Venn diagram could be used to compare the similarities and differences between a city and town by writing each in a separate circle and noting shared and unique characteristics in the respective areas.

Write similarities of the words in the joined or center portion of the circles, and
