UK[ˈluːpəs]US[ˈluːpəs]
n

n
(capitalized, in astronomy) a southern constellation (the wolf).
Etymology
the word 'lupus' entered english directly from latin, where it means 'wolf'. its application to the disease has a long and vivid history. in the 10th century, the physician herbert described ulcerative lesions on the legs as being 'voracious as a wolf', a metaphor later formalized in medieval latin as 'lupus vulgaris'. this descriptive logic, likening the disease's destructive nature to a wolf's attack, solidified the name. the astronomical constellation 'lupus' was cataloged by ptolemy in the 2nd century, preserving the latin term for the animal in the celestial sphere.
Analysis
the word is a direct latin loanword and is not productively segmented into smaller meaningful parts in modern english spelling.
