I can't put this sentence together and have it sound right. Any suggestions?

Women have contributed much to American culture of great value. or

Women have contributed much of great value to American culture.

HELP!

Your second sentence is better.

You could shorten it to:

Women have contributed much to American culture.

You could put:Women have been a great contributor to American culture.

Both of your sentence formulations are grammatically correct, and the meaning conveyed is quite similar. However, if you are seeking a suggestion to make the sentence flow better, here's an option:

"In American culture, women have made significant contributions of great value."

This rephrasing rearranges the sentence structure slightly, placing more emphasis on the contributions made by women. It also provides a smoother flow by introducing "American culture" earlier in the sentence.

Remember, sentence structure and word choice can vary depending on context and personal style, so feel free to experiment with different variations until you achieve the desired result.
