Learn Hardcore German: Wir treffen uns wenigstens für zehn Minuten im Park. - We meet for at least ten minutes in the park.

Because sich treffen is used reciprocally: Wir treffen uns means “we meet each other.” Without uns, Wir treffen is incomplete or means something else (e.g., “we hit” or “we are correct/right” in some contexts). If you meet a third person, you’d say Wir treffen ihn/sie/sie (pl.) instead.

Is uns accusative or dative in this sentence?

Accusative. The verb treffen takes an accusative object, and with “purely reflexive” use (no second object), the reflexive pronoun is in the accusative: wir – uns. It would only be dative if there were another accusative object (e.g., with verbs like sich die Hände waschen).

Can I say Wir treffen einander instead of Wir treffen uns?

It’s possible but uncommon and a bit stiff. The natural, everyday way is Wir treffen uns. You might use einander for stylistic variety or emphasis, but most Germans prefer the reflexive here.

What’s the difference between sich treffen, treffen (jemanden), begegnen (jemandem), sich sehen, and kennenlernen?

sich treffen: to meet each other (usually arranged). Example: Wir treffen uns im Park.
treffen (jemanden): to meet (someone) or to hit/affect. Example: Wir treffen ihn morgen.
begegnen (jemandem) (dative): to run into someone by chance. Example: Ich bin ihm im Park begegnet.
sich sehen: to see each other (can be accidental or planned). Example: Wir sehen uns später.
kennenlernen: to meet for the first time / get to know. Example: Wir haben uns 2020 kennengelernt.

Why is the verb treffen in second position?

German main clauses follow the “verb-second” (V2) rule: one element (here, Wir) comes first, then the finite verb (treffen), then the rest of the clause (uns wenigstens …). You can front a different element for emphasis, but the finite verb still stays second: Wenigstens treffen wir uns …

Where can wenigstens go, and what does it modify here?

Here it precedes and scopes over the time phrase: wenigstens für zehn Minuten. Other natural positions:

Wenigstens treffen wir uns … (at least we do meet)
Wir treffen uns für wenigstens zehn Minuten … (at least ten minutes) Each position slightly shifts the emphasis/scope.

What’s the difference between wenigstens, mindestens, and zumindest in this context?

wenigstens: “at least” in a consoling/concessive sense (“not ideal, but better than nothing”): wenigstens für zehn Minuten.
mindestens: a hard lower bound (“no less than”): mindestens zehn Minuten; neutral/quantitative.
zumindest: “at least” as a hedge/restriction of scope, often more formal: zumindest für zehn Minuten (similar to wenigstens, but less “consoling” in tone).

Why für zehn Minuten and not zehn Minuten lang? Can I omit für?

für zehn Minuten = for a duration of ten minutes (planned/allocated span).
zehn Minuten lang = lasting ten minutes (emphasis on actual duration). With sich treffen, both are heard; many speakers prefer für here. You will also hear Wir treffen uns zehn Minuten … without für, but the safest learner choice with meeting is to include für.

Which case does für take, and why is it zehn Minuten?

für always takes the accusative. Minute is feminine; plural is Minuten. So: für zehn Minuten (accusative plural).

Why is it im Park and not in den Park?

German in is a two-way preposition:

Dative for location (where?): im Park (= in dem Park) — we are in the park.
Accusative for direction (into/where to?): in den Park — we’re going into the park. Since this sentence describes location of the meeting, dative is correct.

What exactly is im?

A contraction of in dem. So im Park = in dem Park. Both are correct; the contraction is more common in speech and writing.

Could I say am Park instead of im Park?

Only if you mean “at/by the park” (near it, not inside). am = an dem and typically means “at (the edge of)/by.” im Park means “in(side) the park.”

Is the order für zehn Minuten (time) before im Park (place) important?

Yes, it follows the default “time before place” preference in German. You can swap them for emphasis (e.g., Im Park treffen wir uns wenigstens für zehn Minuten), but the given order sounds neutral and natural.

Is treffen irregular? How do I conjugate it?

Yes, it’s irregular (stem vowel change). Present: ich treffe, du triffst, er/sie/es trifft, wir treffen, ihr trefft, sie treffen. Past: ich traf …; Participle II: getroffen.

How would I say this in the past or perfect tense?

Simple past: Wir trafen uns wenigstens für zehn Minuten im Park.
Present perfect: Wir haben uns wenigstens für zehn Minuten im Park getroffen. In the perfect, the participle getroffen goes to the end, and you use haben as the auxiliary.

Do I need a comma anywhere in this sentence?

No. It’s a single main clause with no additional clauses or elements that require commas in German.
