An Etymological Dictionary of the German Language/Annotated/Staude
Staude, feminine, ‘shrub, bush,’ from the equivalent Middle High German stûde, Old High German stûda, feminine, a specifically High German word, wanting in the other Teutonic dialects. Its genuine Teutonic origin is, however, undoubted. It seems, like stehen, to belong to a primitively cognate Aryan root stū̆, which appears in Greek στῦλος, ‘pillar,’ and στῦω, ‘to look fixedly,’ and so in stützen.
