sco·toma
noun
1.
an epicycloid in which the rolling circle equals the fixed circle
Origin
From Late Latin scotoma, from Ancient Greek σκότωμα (skótōma), from σκότος (skótos, “darkness”). By surface analysis, scot- + -oma. The figurative sense is an extension from the literal sense, as if the mind, like an eye, cannot "see" certain things.
