Etymology

Origin of willow

First recorded before 900; Middle English wilwe, variant of wilghe, Old English welig; cognate with Old Saxon wilgia, Dutch wilg, Low German wilge

Explanation

A willow is a tree with long, flexible branches and very small leaves. If you're looking for a picnic spot, the wide, green canopy of a willow provides great shade on a hot summer day. Most willow trees grow near water or in damp locations, as their roots soak up great quantities of moisture and can be used to protect the banks of rivers and streams from erosion. Willow branches are also commonly woven together to make baskets. A "weeping willow" has distinctive, graceful branches that curve down toward the ground.
