Questions & Answers about אם הפעמון לא עובד, תתקשרי אליי כשתגיעי.
Because the sentence is addressed to one female person.
Both תתקשרי and תגיעי are 2nd person feminine singular forms.
- תתקשרי = you (feminine singular) will call / call
- תגיעי = you (feminine singular) will arrive
If you were talking to a man, you would say:
- תתקשר
- כשתגיע
If you were talking to more than one person, you would usually say:
- תתקשרו
- כשתגיעו
Hebrew usually doesn’t need subject pronouns like you, I, she, etc., because the verb form already shows who the subject is.
So תתקשרי already means you (feminine singular) call / will call, and תגיעי already means you (feminine singular) arrive / will arrive.
You could add את for emphasis:
- אם הפעמון לא עובד, את תתקשרי אליי כשתגיעי.
But normally that sounds unnecessary unless you want contrast or emphasis.
