opsimath

n. person who start to study or acquires knowledge late in life; late learner

An opsimath can refer to a person who begins, or continues, to study or learn late in life. The word is derived from the Greek οπσε (opse), meaning 'late' and μανθανω (manthano), meaning 'learn'.Opsimathy was once frowned upon, used as a put down with implications of laziness, and considered less effective by educators than early learning. However, the opsimath population is increasing in the USA, and the emergence of "opsimath clubs" proves that opsimathy is no longer looked down upon, but is in fact desirable.
