look up any word, like the eiffel tower:
The inability for technically capable people to learn from manuals, while being perfectly capable of learning by watching someone do something or by being walked through it.

From the prefix "dys", meaning 'bad' or 'ill'; "tech" as a short form of 'technology'; "lex" either from 'lex' meaning rule or law, or 'lexis' meaning the totality of words and their combinations in a language; and 'ia' as the connective suffix. Not to be confused with techlexia. Derived in part from "dyslexia"
She is capable of learning how to operate the machine perfectly by watching someone else use it, but her dystechlexia keeps her from learning from a written manual.
