Other forms: opsimaths
Someone who begins studying or learning later in life, defying typical timelines or expectations, is called an opsimath.
The meaning of the word opsimath comes from the Greek words meaning "late" and "learn." Opsimaths embody the idea that it’s never too late to learn something new, proving that curiosity and growth have no age limit. This might include someone pursuing a college degree in their golden years, mastering a new skill after retirement, or learning about a subject they’ve always been curious about.
