schwänzen vs fehlen
to be absent / to be missing
'fehlen' and 'schwänzen' can both mean that someone is not at a class or a mandatory event. 'fehlen' is neutral: the person is not present, but the reason could be illness, vacation, or something else. 'schwänzen' is colloquial and means that someone deliberately and without permission stays away. Learners may confuse the words because both are used in connection with school or appointments. If you are not judging the reason, use 'fehlen'. If it is clear that someone intentionally does not come even though they have to, use 'schwänzen'.
