Why is the ninth month called September?
Old English elm, from Proto-Germanic *elmaz (cf. Danish elm, Old Norse almr, Old High German elme), perhaps from PIE root *el- "red, brown" (see elk); cognate with Latin ulmus, Old Irish lem. German Ulme, Dutch olm are from or influenced by the Latin word.
Hos. 4:13; rendered "terebinth" in the Revised Version. It is the Pistacia terebinthus of Linn., a tree common in Palestine, long-lived, and therefore often employed for landmarks and in designating places (Gen. 35:4; Judg. 6:11, 19. Rendered "oak" in both A.V. and R.V.). (See TEIL TREE.)
