Not covered or protected from sunlight; exposed to light without any shadow.
The unshaded area of the garden gets very hot during the summer.
Unshaded → It is formed from "un-" (meaning not) and "shaded" (from Old English "sceadu", meaning shadow or shade). The word "unshaded" means not covered by shade or shadow.
Think of 'not' ('un-') being added to 'shade' — so unshaded means there is no shade.
