Der Gangplatz ist direkt neben dem Notausgang.

Literally, Gangplatz is made of:

• der Gang = aisle
• der Platz = seat, place, or spot

So der Gangplatz means aisle seat.

It is understandable and used, especially in travel contexts, but in some situations German speakers may also say ein Platz am Gang. Both refer to a seat next to the aisle.

Der Gangplatz is the subject of the sentence, so it comes in the nominative case.

The basic structure is:

• Der Gangplatz = the aisle seat
• ist = is
• direkt neben dem Notausgang = directly next to the emergency exit

So the sentence follows a very normal German pattern:

subject + verb + the rest

Because Gangplatz is a masculine noun: der Gangplatz.

In German, every noun has a grammatical gender, and this does not always match natural logic. You simply have to learn the noun together with its article:

• der Gangplatz
• der Notausgang

That is why the sentence begins with Der Gangplatz.

This is one of the most common grammar questions.

The preposition neben can take either:

• dative for location
• accusative for movement toward something

Here, the sentence describes a fixed location: the seat is next to the emergency exit. There is no movement. So German uses the dative:

• neben dem Notausgang = next to the emergency exit

Compare:

• Der Sitz ist neben dem Notausgang. = The seat is next to the emergency exit.
  Location → dative

• Ich setze mich neben den Notausgang.
  This would suggest movement toward that position, so accusative would be used, though this exact example is not very natural in real life.

The basic noun is der Notausgang.

Because neben here requires the dative, der changes to dem:

• nominative: der Notausgang
• dative: dem Notausgang

So:

• neben dem Notausgang

This is a normal article change for masculine and neuter nouns in the dative singular.

Direkt means directly. It adds emphasis and tells you that the aisle seat is immediately next to the emergency exit, not just somewhere nearby.

Compare:

• neben dem Notausgang = next to the emergency exit
• direkt neben dem Notausgang = directly right next to the emergency exit

So direkt strengthens the idea of closeness.

Yes. German forms many nouns by combining smaller words.

Notausgang consists of:

• Not = emergency
• Ausgang = exit

Together, Notausgang means emergency exit.

This is very typical of German. English often uses separate words where German uses one compound noun.

Yes, often you can.

• der Gangplatz = aisle seat
• der Platz am Gang = the seat by the aisle

Both are understandable and natural, depending on context. The compound noun Gangplatz is compact and useful, while Platz am Gang sounds a bit more descriptive.

In a normal German main clause, the finite verb usually comes in second position.

Here the first element is the subject:

• Der Gangplatz = position 1
• ist = position 2

That is standard German word order.

If you moved another element to the front, the verb would still stay second:

• Direkt neben dem Notausgang ist der Gangplatz.

That sounds more marked or stylistic, but it is still grammatical.

A rough pronunciation guide:

• Gangplatz ≈ GAHNG-plahts
• Notausgang ≈ NOHT-ows-gahng

A few useful points:

• g in Gang is a hard g
• platz sounds like plahts
• au in Notausgang sounds like English ow in now
• the ng sound in Gang is like the end of English song

The stress is usually on the first part of these compounds:

• GANGplatz
• NOTausgang
