self-instructional

The word is a modern English compound adjective built from established components. The prefix "self," with ancient Germanic roots, signifies autonomy and reflexivity. It is attached to "instructional," which derives from the Latin verb instruere, meaning "to build, equip, or teach." The literal sense of "building knowledge into someone" evolved into the modern meaning of teaching. Combined, the morphemes logically construct the concept of "relating to teaching directed by oneself," perfectly capturing the method of independent learning without an external instructor.

Structure: self (own) + instruct (teach) + ion + al (adjective suffix) self: Old English, from Proto-Germanic, meaning "one's own person."
