Technical Meanings Can Survive Colloquial Use
Words do not stay inside the boundaries a field gives them. A technical term enters ordinary language and expands to cover related experiences, metaphors, and dramatic changes. The broader use may become perfectly legitimate.
That does not erase a narrower use made for a particular purpose. Transformation, for example, can mean any major change in everyday speech. In a more specific inquiry, it can name a shift in what a person sees as possible, distinct from improvement in existing conditions.
Confusion begins when one use is treated as proof that the other is invalid. Ordinary language can evolve while a field still needs precision.
Before arguing about what a word really means, ask which conversation we are having and what distinction that use of the word is trying to preserve.
