roast, broil, toast, cauterize
炙 centers on applying direct heat to something, typically from above or below, to cook or treat it: roasting, broiling, toasting, or cauterizing.
炙 combines 肉 (meat, simplified to 夕 in the modern form) above 火 (fire), depicting meat being roasted over a fire.
Picture a slice of meat (the top part, like 夕 with a dot) placed over a fire (火) to roast it until it sizzles.
For シャ, imagine roasting meat over a fire while sitting in the shade (シャ) of a tree: shade -> シャ, and the fire roasts the meat.
