After looking at the two-way preposition in last week, let's continue our series with an. This preposition is also a two-way preposition and is used in a multitude of contexts, including with the accusative case to express movement from one place to another.
We use an rather than nach or in in some contexts where we will end up next to or to the side of something rather than in or on it.

An is also used when we are going to a place that forms a boundary or edge. In particular, you can memorize an die Küste and an den Strand.
Natali und Florian zieht es zunächst an die Küste Cornwalls.
Natali and Florian proceed first to the coast of Cornwall.Play Caption

Other places/nouns that are commonly paired with the preposition an when they are the destination include die Kreuzung (the intersection), die Wand (the wall), and die Grenze (the border). With all three of these examples, an + the accusative is only used when the barrier is NOT being crossed or traversed and it is simply a matter of going/driving/walking "up to" it. When you see an on Yabla German, you can quickly note whether it's being used with the accusative to mean "to" or with the dative to mean "at" or "on." Don't forget, however, that an also appears in contexts that have nothing to do with going or being anywhere (for example, an etwas denken).
