A common mistake for Spanish speakers is to use the Present Simple or Past Simple instead of the Present Perfect with for و since.
- خطأ: I live here for two years.
- الصحيح: I have lived here for two years.
Another mistake is confusing for و since. تذكر،, for is for the length of time, and since is for the moment it started.
- خطأ: I have studied English since three months. (Use for with 'three months' because it's a duration.)
- الصحيح: I have studied English for three months.
- الصحيح: I have studied English since March. (Use since with 'March' because it's a starting point.)
الأسئلة الشائعة
Can I use 'for' and 'since' with other tenses?
No, for A1 English, you will primarily use for و since with the Present Perfect tense to talk about actions that started in the past and continue now.
What is the difference between 'for a long time' and 'since a long time'?
You should always say for a long time. A long time is a duration, so we use for. We do not say since a long time.
Is 'have been' the same as 'have lived'?
Not exactly. Have been is the Present Perfect of the verb to be. Have lived is the Present Perfect of the verb to live. Both can be used with for و since. على سبيل المثال،, I have been here for an hour أو I have lived here for an hour.
