feather Scientific  
/ fĕth′ər /
  1. One of the light, flat structures that cover the skin of birds. A feather is made of a horny substance and has a narrow, hollow shaft bearing flat vanes formed of many parallel barbs. The barbs of outer feathers are formed of even smaller structures (called barbules) that interlock. The barbs of down feathers do not interlock. Evolutionarily, feathers are modified scales, first seen in certain dinosaurs.

Etymology

Origin of feather

before 900; Middle English, Old English fether; cognate with Dutch veder, German Feder, Old Norse fjǫthr; akin to Greek pterón, Sanskrit pátram wing, feather

Explanation

A feather is one of the soft, fringed plumes that cover the bodies of birds. Some feathers are tiny and downy, while others are large and brilliantly colored. Feathers are the main characteristic that separates birds from all other animals. Scientifically, feathers are described as growths or appendages that form on a bird's skin — but this definition can't capture how lovely feathers are. When feather is a verb, it usually means to turn or rotate an oar, paddle, or propeller so that it's parallel to the surface of the water.
