Informally, super means very good or extremely, as in 'super fun'. As a noun, it can mean a building superintendent.
From Latin 'super' meaning 'above, over, beyond'. The 'very, extremely' sense comes from the idea of going above the normal level.
Every 'superhero' and 'superpower' borrows that Latin idea of being 'above and beyond' ordinary humans. When teens say 'super tired' or 'super chill', they’re casually using a tiny piece of ancient Latin intensity.
