Morphology
The sense 'sane; thinking sensibly' can be partly inferred from 'right' (proper/correct) + 'mind' (the faculty of thinking) as meaning a properly functioning mind, so a learner who knows the constituents may guess a related sense. However, the idiomatic phrasing and the specific sense 'not crazy' is a conventionalized extension of 'right' that is not fully predictable and shows cross‑linguistic variation, making it only partly transparent to B1 learners.
Etymology
In her right mind paints a simple picture: her mind is right, meaning correct and working well rather than confused. So, to say someone is in her right mind means she is 'thinking clearly' and not acting in a wild or unsafe way.
