Why is the ninth month called September?
"any small ship," early 15c., from Middle French barque (15c.), from Late Latin barca (c.400 C.E.), probably cognate with Vulgar Latin *barica (see barge). More precise sense of "three-masted ship" (17c.) often is spelled barque to distinguish it.
dog sound, Old English beorc, from bark (v.). Paired and compared with bite (n.) since at least 1660s; the proverb is older: "Timid dogs bark worse than they bite" was in Latin (Canis timidus vehementius latrat quam mordet, Quintius Curtius).
in reference to a dog sound, Old English beorcan "to bark," from Proto-Germanic *berkanan (cf. Old Norse berkja "to bark"), of echoic origin. Related: Barked; barking. To bark up the wrong tree is U.S. colloquial, first attested 1832, from notion of hounds following the wrong scent.
The protective outer covering of the trunk, branches, and roots of trees and other woody plants. Bark includes all tissues outside the vascular cambium. In older trees, bark is usually divided into inner bark, consisting of living phloem, and outer bark, consisting of the periderm (the phelloderm, cork cambium, and cork) and all the tissues outside it. The outer bark is mainly dead tissue that protects the tree from heat, cold, insects, and other dangers. The appearance of bark varies according to the manner in which the periderm forms, as in broken layers or smoother rings. Bark also has lenticels, porous corky areas that allow for the exchange of water vapor and gases with the interior living tissues.
