self-instruction

The compound "self-instruction" is a modern English formation that logically combines two established elements. The first element, "self," is a deeply rooted Germanic word from Proto-Indo-European selbʰ-, carrying the core sense of one's own person. The second, "instruction," entered English via Old French from Latin instruere, which originally meant "to build, pile up, or arrange," a sense derived from struere (to pile, build). The semantic evolution from physical construction to mental preparation and teaching is a classic metaphorical shift. Therefore, "self-instruction" literally means "building up (knowledge) by oneself," perfectly capturing the modern concept of autonomous learning where the individual arranges and acquires their own education.

Structure: self (own) + instruction (teaching) self: From Old English self, seolf, sylf, meaning "own, same." It functions as a prefix indicating something directed at, by, or for oneself. instruction: From Latin instructio (a building, arrangement, teaching), from instruere (to build, arrange, teach). It functions as the core noun meaning the act or process of teaching.
