Question

Where do I put the comma in the sentence This book describes the harsh isolated lives of pioneer women in Kansas.

Answer 1

The comma would go after harsh and before isolated:

This book describes the harsh, isolated lives of pioneer women in Kansas.

Multiple adjectives must be separated with a comma, thus the comma goes between the adjectives in this sentence (harsh and isolated).

Answer 2

This book describes the harsh, isolated lives of pioneer women in Kansas
