Learn Hardcore German: Der Verein plant eine Feier im Park. - The club is planning a celebration in the park.

im is a contraction of in dem. You use dative (dem) with in when you’re talking about location (where something is). Since Park is masculine, you get in dem Park → im Park. For movement into something (direction), in takes the accusative: masculine/neuter contract to ins (in das).

Location: Sie sitzen im Park.
Direction: Sie gehen in den Park. / Sie gehen ins Haus.

Why is it eine Feier and not ein Feier?

Because Feier is a feminine noun. The feminine indefinite article is eine in both nominative and accusative. Here, eine Feier is the direct object (accusative), and feminine accusative is also eine.

Nominative fem.: eine Feier beginnt.
Accusative fem.: Er plant eine Feier.

Why der Verein and not den Verein?

Der Verein is the subject, so it’s in the nominative case. Masculine nominative uses der. You’d use den for masculine accusative (when it’s a direct object):

Subject: Der Verein plant …
Object: Der Bürgermeister lobt den Verein.

Does plant mean “plants” (like a tree) in German?

No. plant is the 3rd person singular present of planen (to plan). Don’t confuse it with pflanzen (to plant). Mini conjugation of planen in the present:

ich plane
du planst
er/sie/es plant
wir planen
ihr plant
sie/Sie planen

German present often covers English “is planning” as well as “plans.”

What cases are used in this sentence?

Der Verein: nominative (subject), masculine → der
eine Feier: accusative (direct object), feminine → eine
im Park: dative (location with in), masculine → in dem → im

Can I change the word order, like putting the place earlier?

Yes. German is flexible, but the finite verb stays in the 2nd position (V2 rule). You can shift elements for emphasis:

Neutral: Der Verein plant eine Feier im Park.
Emphasis on place: Im Park plant der Verein eine Feier.
Emphasis on what’s planned: Eine Feier plant der Verein im Park.

How do I negate this sentence correctly?

Two common options, with different meanings:

No party is being planned in the park: Der Verein plant keine Feier im Park. (replace the indefinite article with keine)
The party is planned, but not in the park: Der Verein plant die Feier nicht im Park. (nicht negates the place; definite article implies a specific party)

What’s the difference between im Park and in den Park?

im Park (dative): location (where?) → inside the park.
in den Park (accusative): direction (where to?) → into the park.

Think “static” vs “movement.”

Is am Park possible, and how does it differ from im Park?

Yes. am = an dem (dative). am Park means at or by the park (adjacent to it), while im Park means inside the park.

Die Feier ist am Park. (next to/at the park)
Die Feier ist im Park. (within the park)

How do I pronounce tricky parts like Verein and Feier?

Verein: initial V is pronounced like English “f”; ei sounds like “eye”; stress on the second syllable → fe-REIN.
Feier: ei = “eye”; two syllables → FYE-er.
plant: “plahnt” (broad a), not like English “plant” with a short “a.”
Park: “pahrk,” with a German r.
im: like English “im.”

What’s the nuance between Verein and Club/Klub?

Verein: an association/society, often formal or legally registered (eingetragener Verein, e.V.). Common for hobby, cultural, and sports associations.
Club/Klub: can be a sports club or social club; Club is common spelling; Klub also exists. In some contexts (e.g., nightlife), Club ≈ nightclub. In many sports names you’ll see both (e.g., Fußballclub vs Sportverein), with slight stylistic/branding preferences.

What’s the difference between Feier, Party, and Fest?

Feier: general “celebration,” often neutral/formal (e.g., Betriebsfeier, company celebration).
Party: casual social gathering; more colloquial/modern.
Fest: larger, often public event/festival (e.g., Volksfest, Weinfest). Also used in compounds like Hochzeitsfest.

How would I say this in the past or future?

Simple past (Präteritum): Der Verein plante eine Feier im Park. (common in writing)
Present perfect (Perfekt): Der Verein hat eine Feier im Park geplant. (very common in speech)
Future (Futur I): Der Verein wird eine Feier im Park planen. Note: German often uses the present with a future time expression: Der Verein plant nächste Woche eine Feier im Park.

Can I use planen with a “to do” clause, or should I use vorhaben?

Both work, with slightly different patterns:

planen, with a direct object or a zu-infinitive clause:
- Der Verein plant eine Feier im Park.
- Der Verein plant, im Park zu feiern.
vorhaben (“to intend”), typically with a zu-infinitive:
- Der Verein hat vor, im Park zu feiern. You usually don’t say eine Feier im Park vorhaben; prefer the zu-infinitive with vorhaben.

Are the nouns capitalized for a reason?

Yes. All nouns in German are capitalized: Verein, Feier, Park. The sentence-initial Der is capitalized because it starts the sentence; otherwise articles are lowercase.

What are the plural forms and some useful case forms of the nouns?

der Verein → plural: die Vereine; genitive sg.: des Vereins; dative sg.: dem Verein; dative pl.: den Vereinen
die Feier → plural: die Feiern; genitive sg.: der Feier; dative pl.: den Feiern
der Park → plural: die Parks; dative sg.: dem Park; dative pl.: den Parks (no extra -n because the plural already ends in -s)

If I add adjectives, how do the endings work here?

Feminine accusative with an indefinite article: eine große Feier (ending -e)
Masculine dative with a definite article (inside im = in dem): im großen Park (ending -en) Example: Der Verein plant eine große Feier im großen Park.

How do I form a yes–no question or a “where” question from this sentence?
