Aussengrenze vs Grenze
border / limit
'die Grenze' and 'die Aussengrenze' both refer to a line that separates one area from another. 'Grenze' is the general word and can mean any political or geographic separation. 'Aussengrenze' is more specific: it means the external border of a larger area, for example a union of states like the EU, with countries outside it. The words can be confused because every 'Aussengrenze' is also a 'Grenze'. But not every 'Grenze' is an 'Aussengrenze'. If you are only talking about two neighboring countries, 'Grenze' is usually enough; for the outer line of a larger area, 'Aussengrenze' is more precise.
Aussengrenze
Die Kontrolle an der Aussengrenze der EU dauerte länger als erwartet.
The check at the EU's external border took longer than expected.
Grenze
Kurz vor der Grenze kauft die Familie noch eine Vignette.
Shortly before the border, the family buys a vignette.
