Unterfangen vs Unternehmen
company / undertaking
'das Unternehmen' and 'das Unterfangen' can both mean a planned undertaking, especially when it is difficult or requires a lot of effort. However, 'das Unternehmen' also has another very common meaning: a company. When it means an undertaking, it sounds rather formal or somewhat elevated. 'das Unterfangen' almost always means a difficult or risky undertaking and also sounds formal. In everyday language, people often use simpler words like 'Plan' (plan) or 'Projekt' (project). When talking about a company, only 'das Unternehmen' fits, not 'das Unterfangen'.
