An Etymological Dictionary of the German Language/Rosmarin
Appearance
Rosmarin, m., ‘rosemary,’ first occurs in early ModHG., formed from the equiv. Lat. rosmarinus, whence also Du. rozemarijn and MidE. rosmarine, E. rosemary (implying a connection with Mary); the word in G. and E. is instinctively connected with Rose, ‘rose.’
