What does wetsuit mean?
A wetsuit is a close-fitting garment worn over the body to provide warmth and protection while swimming or working in water. It is usually made from neoprene and is associated especially with diving, surfing, and other aquatic sports. Unlike a drysuit, which is intended to keep external water entirely out, a wetsuit works partly by allowing a small amount of water to enter; the body warms that layer, helping reduce heat loss. The term is also used more broadly for close-fitting protective suits intended for cold or wet conditions. A wetsuit is normally a single noun, and “wet suit” is also encountered as an open spelling. In dictionaries and sporting contexts, a wetsuit refers to the garment rather than to the act of swimming in it. The word is useful because it names a distinctive hybrid: clothing designed to be partly wet in order to make the wearer warmer and more comfortable.

Etymology of wetsuit
The word was formed in English by joining the long-established words wet and suit. It came into general use in the mid-20th century as divers adopted close-fitting suits for protection and warmth in cold water. The second element belongs to the English word family represented by suit and suite, ultimately traceable to Latin sequi, “to follow.”
How wetsuit is actually used
