Grammar for the Well-Trained Mind, Key to the Purple Workbook



This Key to the Purple Workbook, a Purple Workbook, and the Core Instructor Text make up Grammar for the Well-Trained Mind: a complete course that takes students from basic definitions (“A noun is the name of a person, place, thing, or idea”) through advanced sentence structure and analysis—all the grammar skills needed to write and speak with eloquence and confidence.

This innovative program combines the three essential elements of language learning: understanding and memorizing rules (prescriptive teaching), repeated exposure to examples of how those rules are used (descriptive instruction), and practice using those rules in exercises and in writing (practical experience).
