Compare with
Funktion vs Rolle
role / roll
'die Rolle' and 'die Funktion' are close in meaning when talking about what someone or something is there for in a particular context. 'die Funktion' often sounds more factual and precise, especially with devices, things, systems, or official positions. 'die Rolle' is used more often when describing the importance or place of a person or thing in a situation. Learners may confuse the words because both can mean 'what something does'. As a guide: for technology and a clearly defined task, 'Funktion' works well; for people, groups, and contexts, 'Rolle' sounds more natural.
Funktion
Vor dem Termin prüfen wir die Funktion des neuen Druckers.
