Using Present Simple Instead of Present Perfect
Spanish speakers often use the present simple with 'desde hace' or 'desde' to talk about ongoing actions, which is incorrect in English. You must use the present perfect.
- Falsch: I live here for five years.
- Richtig: I have lived here for five years.
- Falsch: She works here since 2020.
- Richtig: She has worked here since 2020.
Using Present Perfect for Finished Actions
Remember, the present perfect with for oder since is for actions that *continue now*. If the action is finished, use the past simple.
- Falsch: I have lived in New York for two years (from 2015 to 2017). (The period is finished.)
- Richtig: I lived in New York for two years (from 2015 to 2017).
Confusing 'For' and 'Since'
This is a very common mistake. Remember the difference:
- For = duration (e.g., for three hours)
- Since = starting point (e.g., since 3 o'clock)
Häufig gestellte Fragen
What is the main difference between 'for' and 'since'?
The main difference is that for tells you the *length of time* (duration), like for two weeks. Since tells you the *starting point* in time, like since Monday. Both are used with the present perfect for actions that continue now.
Can I use 'for' or 'since' with other tenses?
Yes, but with different meanings. For example, you can use for with the past simple for a finished duration: I lived there for five years (but I don't live there now). You can also use since with the past simple to indicate a reason: Since it was raining, we stayed inside. However, for actions continuing to the present, the present perfect is usually required with for und since.
Are there any verbs that cannot be used with 'for' and 'since' in the present perfect?
Generally, verbs that describe short, completed actions (like arrive, start, finish) are less common with for und since in the present perfect, unless they are part of a continuous state. For example, you wouldn't say I have arrived for two hours. Instead, verbs that describe states or ongoing activities (like live, study, be) are typical.
