Word Origin and History for rickets

rickets

n.

disease caused by vitamin D deficiency, 1630s, of uncertain origin. Originally a local name for the disease in Dorset and Somerset, England. Some derive it from a Dorset word, rucket "to breathe with difficulty," but the sense connection is difficult. The Modern Latin name for the disease, rachitis, comes from Greek rhakhis "spine" (see rachitic), but this was chosen by English physician Daniel Whistler (1619-1684) for resemblance to rickets.
