Einlauf vs Zugang
access / entrance
'der Zugang' and 'der Einlauf' can both refer to a place through which someone or something enters. 'der Zugang' is the normal, general word for a way, entrance, or access road to a place. 'der Einlauf' is much more specific: it is used, for example, for a harbor or for a technical opening through which water, air, or another substance enters. For people in front of a house, you would normally say 'Zugang' or 'Eingang', not 'Einlauf'.
