What does scaly mean?
Scaly is an adjective meaning covered with scales, the small, hard, overlapping plates found on the skin of many fish, reptiles, and amphibians. It is also used to describe skin that is unusually dry, rough, or beginning to peel, especially in cold or irritated conditions. The literal animal sense is the most common and is readily understood: a fish has scaly skin, while a snake or lizard has a scaly body. In descriptions of people, the word tends to be factual and somewhat clinical, focusing on texture rather than attractiveness. Because “scaly” directly evokes a visible surface made of overlapping plates, it can also be used figuratively, though such literary uses are less frequent. The word is related to “scale,” the thin plate or protective covering, and ultimately derives from an Old English word for a fish’s scale.
Covered with or marked by scales; having a surface composed of small overlapping plates.
"The snake's scaly body glinted in the sunlight."
This is the primary literal sense and is especially common in descriptions of fish, reptiles, and amphibians.
Describing skin that is dry, rough, and peeling or flaking.
"The cold weather left her hands dry and scaly."
Usually neutral and factual; it may sound somewhat clinical when applied to human skin.
A reptile's skin is not merely scaly: the scales help regulate body temperature and protect it from injury and water loss.

Where does scaly come from?
The adjective “scaly” was formed in English by adding the suffix “-y” to “scale.” The noun “scale” comes from Old English “scale,” meaning a fish’s scale or a thin plate, and related forms appear across Germanic languages. The word’s history is therefore tied to the physical plates that cover the bodies of fish and reptiles. The closely related forms “scaleless” and “scalewise” share the same historical root.
