Excellent → It is formed from 'ex-' (meaning out of or from) and 'cella' (meaning a small room or chamber). The word originally described something that stands out or is superior, as if it comes from a higher place or quality.
Think of something that comes 'out of' ('ex-') a 'small chamber' ('cella') as being superior or outstanding — that's why excellent means of high quality.
