The Sentence Diagram Generator can visually represent the grammatical structure of the sentence: "The ultimate purpose, however, is not only to enhance teaching and resulting student learning but also to capacitate the teacher for self-directed learning and to cause the teacher to grow toward higher states of mind."

To create the diagram, input the sentence into the tool, and it will break down the components such as the subject ("The ultimate purpose"), the verb ("is"), and the various phrases and clauses that follow. The generator will illustrate the relationships between the main ideas and supporting details, highlighting the coordination of the phrases introduced by "not only... but also."

For specific diagramming, please use the Sentence Diagram Generator interface to visualize this complex structure accurately.
