Etymology

From the Book of Rites, Book 18 (《禮記·學記》):

故学然后知不足，教然后知困。知不足，然后能自反也；知困，然后能自强也，故曰：教学相长也。 [Classical Chinese, simp.]

From: The Book of Rites, c. 4^th – 2^nd century BCE, translated based on James Legge's version

Gù xué ránhòu zhī bùzú, jiào ránhòu zhī kùn. Zhī bùzú, ránhòu néng zìfǎn yě; zhī kùn, ránhòu néng zìqiáng yě, gù yuē: jiào xué xiàng cháng yě. [Pinyin]

Therefore when he learns, one knows his own deficiencies; when he teaches, he knows the difficulties of learning. After he knows his deficiencies, one is able to turn round and examine himself; after he knows the difficulties, he is able to stimulate himself to effort. Hence it is said, "Teaching and learning help each other."
