Unternehmung vs Unternehmen
company / undertaking
'das Unternehmen' and 'die Unternehmung' are closely related, but they do not always sound equally natural. Both can refer to an economic organization; for that, 'Unternehmen' is much more common today. 'Unternehmung' can also mean a planned undertaking or action, especially when some effort or risk is involved. In this meaning, it is closer to 'Unternehmen' as an undertaking. Learners may confuse the words because they look almost the same. In everyday language, people almost always say 'Unternehmen' for a company. 'Unternehmung' fits better for an undertaking and sounds somewhat more formal or elevated.
