Learn Hardcore German: Der Stundenplan hängt im Flur neben der Tür. - The timetable hangs in the hallway next to the door.

A project schedule or work schedule is more likely der Zeitplan.
A personal to‑do schedule might be der Plan or der Zeitplan, not Stundenplan.

So in most contexts, Stundenplan = class timetable rather than any schedule in general.

Why is it der Stundenplan? How do I know it’s masculine?

In German, every noun has a grammatical gender that you generally need to memorize together with the word.

Stundenplan is masculine, so it takes der in the nominative singular:
- der Stundenplan – the timetable
The plural is:
- die Stundenpläne – the timetables (note the umlaut ä)

There isn’t a fully reliable rule that tells you Stundenplan = masculine; this is mostly vocabulary learning. A good habit is to always learn nouns with their article:

der Stundenplan
der Flur
die Tür

Why is the verb hängt used instead of something like ist?

In German, you often use a more specific verb to describe where something is and in what position. Here:

hängen = to hang / to be hanging

So:

Der Stundenplan hängt im Flur …
= The timetable is (in a hanging position) in the hallway …

You could say:

Der Stundenplan ist im Flur neben der Tür.

This is grammatically correct but less specific. Hängt gives the extra information that it’s hanging up, probably on a wall or noticeboard, not lying on a table or in a drawer.

How does the verb hängen work? Is hängt regular or irregular?

In this sentence, hängt is the 3rd person singular present of hängen.

Present tense:

ich hänge
du hängst
er/sie/es hängt
wir hängen
ihr hängt
sie hängen

There are two related uses:

Intransitive (no direct object) – describing a state:
- Der Stundenplan hängt an der Wand.
  The timetable is hanging on the wall.
Transitive (with a direct object) – putting something up:
- Ich hänge den Stundenplan an die Wand.
  I’m hanging the timetable on the wall.

In modern standard usage, the past forms are:

hat gehangen for the intransitive “to be hanging”
- Der Stundenplan hat immer hier gehangen.
hat gehängt for the transitive “to hang something (up)”
- Ich habe den Stundenplan an die Wand gehängt.

Learners mainly need to remember: hängen – hängt – hat gehangen/gehängt depending on meaning.

What does im Flur mean exactly, and what is im?

Im Flur means “in the hallway”.

im is a contraction:
- im = in + dem
Flur is masculine: der Flur (nominative)
After in (for location), you use the dative:
- in dem Flur → im Flur

So the structure is:

preposition in (location) → dative
masculine dative singular article dem
contraction in dem → im

Why is it dative in im Flur? Could it ever be accusative?

In is a two-way preposition (Wechselpräposition). It can take either:

dative → for location (answering Where? / Wo?)
accusative → for movement into something (answering Where to? / Wohin?)

In the sentence:

Der Stundenplan hängt im Flur …
This describes where it is, so the question is Wo? → dative:
- in dem Flur → im Flur

Compare:

Er hängt den Stundenplan in den Flur.
He hangs the timetable into the hallway. (movement, Wohin? → accusative in den Flur)

So:
Location → dative; movement into → accusative.

What is Flur exactly? Is it the same as corridor or hall?

Der Flur is usually:

a hallway / corridor inside a building
especially the space you walk through between rooms

Near equivalents:

der Flur ≈ hallway, corridor
der Gang, der Korridor – also “corridor”, often in schools, offices, hospitals
die Diele – entry hall / vestibule in a house or apartment

In the sentence, im Flur naturally translates as “in the hallway”.

What does neben der Tür mean, and why is it der Tür and not die Tür?

Neben der Tür means “next to the door”.

The base form is die Tür (feminine, nominative).
neben is another two-way preposition.
Here it expresses location (Where?), so it takes the dative.
Feminine dative singular of die is der.

Cases for die Tür (singular):

Nominative: die Tür (Die Tür ist offen.)
Accusative: die Tür (Ich öffne die Tür.)
Dative: der Tür (Ich stehe vor der Tür.)

So:

neben
- dative (location) → neben der Tür.

Why do both der Stundenplan and der Tür use der, even though one is masculine and the other is feminine?

This is where case vs gender can be confusing:

Der Stundenplan
- Stundenplan is masculine.
- It is the subject of the sentence → nominative case.
- Masculine nominative singular article is der.
- → der Stundenplan
der Tür (in neben der Tür)
- Tür is feminine.
- It is the object of the preposition neben in a location phrase.
- So it is in the dative case.
- Feminine dative singular article is also der.
- → der Tür

So der can mean:

masculine nominative (e.g. der Stundenplan)
or feminine dative (e.g. neben der Tür)

You have to look at both the noun and its role in the sentence to know which is which.

Can I change the word order, for example: Im Flur neben der Tür hängt der Stundenplan?

Yes, that is perfectly correct.

German main clauses follow the verb-second rule:

The finite verb (here hängt) must be in second position in the clause.
Position 1 can be almost anything: the subject, a time phrase, a place phrase, etc.

So you can say:

Der Stundenplan hängt im Flur neben der Tür.
Im Flur neben der Tür hängt der Stundenplan.
Neben der Tür im Flur hängt der Stundenplan. (less natural, but still possible)

In all of them, hängt remains second.

English is stricter about subject-verb order; German is more flexible as long as the conjugated verb stays in position 2.

What other prepositions work like in and neben with dative/accusative?

In and neben belong to a group called two-way prepositions (Wechselpräpositionen). They can take:

dative for location (Wo?)
accusative for movement into / onto (Wohin?)

Common two-way prepositions:

an (at, on [vertical surface])
auf (on [horizontal surface], onto)
hinter (behind)
in (in, into)
neben (next to)
über (above, over)
unter (under)
vor (in front of)
zwischen (between)

Examples:

Der Plan hängt an der Wand. (Where? dative)
Er hängt den Plan an die Wand. (Where to? accusative)

How do you pronounce Stundenplan, Flur, and Tür, especially the ü?

Approximate pronunciation (IPA + tips):

Stundenplan – /ˈʃtʊndənplaːn/
- St at the beginning → “sht” sound.
- u like “oo” in book, not like boot.
- Stress on the first syllable: STUN-den-plan.
Flur – /fluːɐ̯/
- u here is long: like “oo” in food but with German quality.
- Final r is often very weak; it can sound a bit like “floo-uh”.
Tür – /tyːɐ̯/
- ü is the tricky one:
  - Say “ee” as in see (tongue position),
    then round your lips as if saying “oo”.
  - That rounded ee is ü.
- Long ü here: like French “u” in lune.

The r at the end of Flur and Tür is often reduced in everyday speech, depending on region.

Why are Stundenplan, Flur, and Tür capitalized?

In German, all nouns are capitalized, no matter where they appear in the sentence.

So you must always write:

der Stundenplan
der Flur
die Tür

This includes:

names of things (Tisch, Auto, Haus)
abstract nouns (Liebe, Freiheit, Angst)
nominalized words (das Essen, das Lesen, das Reisen)

Capitalization is a strong visual clue that something is a noun, which can actually help you parse sentences once you’re used to it.

Could I leave out the article and say Stundenplan hängt im Flur neben der Tür?

In normal, full sentences, you should not leave out the article here. The natural standard form is:

Der Stundenplan hängt im Flur neben der Tür.

Dropping the article might appear:

in headlines or notes:
- Stundenplan hängt im Flur.
on labels or signs, where very telegraphic style is used.

But in regular spoken or written sentences, Germans nearly always use the article:

Der Stundenplan hängt im Flur … ✔
Stundenplan hängt im Flur … sounds like a headline or note, not like a neutral sentence.
