Frequently Asked Questions
In common usage, they are often used interchangeably. Technically, the lemniscate is the name for the specific figure-eight shaped curve, and the infinity symbol is one of its applications.
The most common pronunciation is /lɛmˈnɪs.kɪt/ (lem-NIS-kit) in American English and /lɛmˈnɪs.kət/ (lem-NIS-kuht) in British English. A less common variant is /ˈlɛm.nɪ.skeɪt/ (LEM-ni-skate).
No, 'lemniscate' is exclusively a noun (and occasionally used attributively as an adjective, e.g., 'lemniscate shape'). It has no standard verb form.
The Lemniscate of Bernoulli, named after the Swiss mathematician Jacob Bernoulli. It is the locus of points where the product of distances from two fixed foci is constant.
A closed, figure-eight-shaped curve that is the symbol for infinity (∞) in mathematics.
Lemniscate is usually formal / technical in register.

Idioms & Phrases
- “[No common idioms. The symbol itself is idiomatic for 'infinity' or 'forever']”
Learning
Memory Aids
Mnemonic
Think 'LEM(N) IS LATE' → Imagine a lazy lemur running late, tracing a lazy figure-eight (∞) path because it can't decide which way to go, symbolising infinite dithering.
Conceptual Metaphor
THE LEMNISCATE IS ENDLESSNESS / THE LEMNISCATE IS PERPETUAL MOTION.
