What does ansae mean?
Ansae is the plural form of the Latin noun ansa, meaning 'handle', adopted into English chiefly within scientific vocabulary. Its most familiar modern use is in astronomy: when Saturn's rings stretch out on either side of the planet's disc through a telescope, they form two handle-like projections known as the ansae, a feature first observed by Galileo in 1610 and famously described by Christiaan Huygens in explaining the ring system. The word also appears in anatomy, where an ansa denotes a loop-shaped structure such as a nerve loop (for example, the ansa cervicalis), with ansae serving as its plural. Because it derives directly from Latin, ansae retains its classical inflected form rather than taking an English-style plural. It is a formal, technical term, rarely heard outside specialist contexts, but valuable to readers of astronomical or anatomical literature.

"Early observers were puzzled by Saturn's ansae, which appeared and disappeared as the rings changed their tilt."
"In anatomical nomenclature, an ansa is a nerve loop, and its plural form is ansae."
Ansae is itself the plural form, retaining the Latin plural ending; the singular is ansa.
"Both ansae were visible during Saturn's opposition."
Galileo spotted Saturn's ansae in 1610 but couldn't work out what they were, writing that the planet seemed to have 'ears'.
