Other forms: pergolas
A pergola is a wooden structure in a garden that's made for climbing plants. For example, you might have an ivy-covered pergola in your yard.
Other words for pergola are trellis or arbor. When gardeners plant climbing roses or ivy or other plants that like to wind upward around supports as they grow, they often use a pergola. The frame holds the vines and also provides a decorative arch that looks pretty in a garden or yard. The word pergola is Italian, from the Latin pergula, "projecting roof," which is most likely rooted in pergere, "to come forward."
