scorch
To burn the surface of something so it turns dark.
Scorch means to burn something's surface, leaving a brown or black mark but not completely destroying it. When you leave an iron on a shirt too long, you might scorch the fabric, creating a dark stain. If you forget cookies in the oven, they come out scorched on the bottom: burned, but not turned to ash.
The sun can scorch grass during a drought, turning lawns brown and crispy. A dragon's breath might scorch the ground without setting it on fire. The word captures that in-between state: damaged by heat, marked by burning, but still recognizable.
People also use scorching to describe extreme heat itself. A scorching summer day feels so hot you can barely stand being outside. When something moves incredibly fast, you might say it scorches across the landscape, like a runner who scorches past the competition.
In sports, a scorching shot means a ball hit or thrown with tremendous speed and power. You can feel the intensity behind the word: fierce, hot, and a little dangerous.
