"Reduced to ashes" is a common phrase used to describe the destruction of something by fire. However, there are other words that can be used instead of this overused phrase. These include "incinerated," "consumed," "burned to a crisp," "charred," "razed to the ground," and "turned to cinders." These synonyms can add more creativity and depth to your writing, particularly in situations where you don't want to keep repeating the same phrase over and over again. Whatever your choice of words, they should effectively capture the severity of the destruction caused by fire.
