Aneurysm

/ˈænjərɪzəm/noun

A bulge in the wall of a blood vessel where the wall has weakened.

The Greek roots

ἀνά
aná
up, throughout
+
εὐρύς
eurýs
wide, broad

Literally: a widening out

The story of the word

ἀνεύρυσμα means simply a widening-out, from εὐρύς, wide, and Greek physicians already used it for a swollen vessel and knew what happened when one gave way. English has spelled it aneurism for centuries by analogy with the crowd of words in -ism, which is an error the dictionaries now mostly correct. The y is there because the second element is εὐρύς, not because anything is being made into a doctrine.
