Time expressions: vor, seit, schon
7-1: Time expressions: vor, seit, schon
🧭 Overview
🧠 One-sentence thesis
German uses three different time expressions—vor (ago), seit (since), and schon (for/already)—each with distinct grammatical cases and tense requirements to express when actions happened or how long they have been ongoing.
📌 Key points (3–5)
- vor + dative = "ago": expresses completed actions in the past (e.g., "ten minutes ago").
- seit + dative = "since": describes ongoing actions that started in the past and continue now; requires present tense in German (unlike English past tense).
- schon + accusative = "for/already": alternative to seit for ongoing actions; also requires present tense and takes accusative case.
- Common confusion: German uses present tense with seit/schon because the action is still happening; past tense would mean you stopped doing it.
- Case distinction matters: vor and seit take dative; schon takes accusative.
⏰ Using vor for past time
⏰ What vor means with time
When used with time expressions, vor means "ago" and is always followed by the dative case.
- You already learned vor as a two-way preposition meaning "in front of."
- With time, it shifts meaning to express how long ago something happened.
- The action is completed in the past.
📋 Examples and pattern
| Time expression | Case | Example sentence | English |
|---|---|---|---|
| vor zehn Minuten | dative | Josephine ist vor zehn Minuten aufgestanden. | Josephine got up ten minutes ago. |
| vor einem Monat | dative | Wir haben vor einem Monat ein neues Haus gekauft. | We bought a new house one month ago. |
| vor fünfzehn Jahren | dative | — | fifteen years ago |
| vor einer Stunde | dative | — | one hour ago |
- Pattern: vor + dative time expression
- Always use past tense (conversational past or simple past) because the action is finished.
🔄 Using seit for ongoing actions
🔄 What seit means
Seit is a dative preposition meaning "since the time of" or "for (duration)"; it describes how long you have been doing something that you are still doing.
- Key difference from English: German uses present tense, not past tense.
- Why? Because you haven't stopped the action yet—it's still ongoing.
⚠️ Tense trap: present, not past
Critical rule: Use present tense with seit, even though English uses present perfect ("have been doing").
| German (present tense) | English (past tense) |
|---|---|
| Wir wohnen seit vier Monaten in Alabama. | We have been living in Alabama for four months. |
| Wir lernen seit zwei Jahren Deutsch. | We have been learning German for two years. |
- Don't confuse: If you used past tense in German, it would mean you stopped living there or stopped learning German.
- Example: "Wir wohnten in Alabama" = "We lived in Alabama (but don't anymore)."
📋 Case requirement
- Seit is a dative preposition, so the time expression following it must be in dative case.
- Example: seit vier Monaten, seit zwei Jahren.
🔁 Using schon as an alternative
🔁 What schon means
- Schon also expresses ongoing duration ("for" or "already").
- Like seit, it implies the action is still happening, so you must use present tense.
- Key difference: schon takes accusative case, not dative.
📋 Comparison: seit vs. schon
| Feature | seit | schon |
|---|---|---|
| Meaning | since / for | for / already |
| Case | dative | accusative |
| Tense | present | present |
| Example | Ich wohne seit einem Jahr hier. | Ich wohne schon ein Jahr hier. |
- Both mean "I have been living here for one year."
- Notice the case difference: seit einem Jahr (dative) vs. schon ein Jahr (accusative).
🔗 Combining schon and seit
- You can use both together to emphasize "since": schon seit.
- Example dialogue:
- A: Wie lange wohnst du schon hier?
- B: Ich wohne schon ein Jahr hier.
- A: Schon so lange? Ich wohne schon drei Monate hier.
- The excerpt mentions a listening example where someone uses schon seit together to emphasize duration.
🎯 Why tense matters
🎯 Ongoing vs. completed actions
The tense choice signals whether the action continues or has stopped:
| Situation | Tense | Example |
|---|---|---|
| Still doing it now | present | Ich lerne seit zwei Jahren Deutsch. (I'm still learning.) |
| Stopped in the past | past | Ich lernte Deutsch. (I learned it but stopped.) |
- This is why the excerpt emphasizes "PRESENT TENSE!!!!!" with seit and schon.
- The listening exercise asks: "Why does he use present tense as opposed to past tense with this 'schon seit' statement?" Answer: because the action is ongoing.
- "Why does he use past tense with the last statement?" Answer: because that action is completed.
🧩 Don't confuse the cases
- Students often forget case distinctions.
- Quick reminder:
- vor (ago) → dative
- seit (since/for) → dative
- schon (for/already) → accusative
- The excerpt includes review exercises on nominative vs. accusative and dative prepositions to reinforce these distinctions before moving forward.
