Questions & Answers about ההודעה שלה הפתיעה אותי, כי לא ציפיתי לתשובה מיד.
Because her message is definite. In Hebrew, possessed nouns are usually definite, so you often get the + noun + possessive, literally the message of hers.
So:
- ההודעה שלה = her message
- הודעה שלה = more like a message of hers
Also, the two ה letters are not a mistake:
- the first ה is the definite article the
- the second ה is part of the noun הודעה
שלה means hers / of her.
It comes after the noun, so Hebrew says:
- ההודעה שלה = literally the message of hers
This is a very common Hebrew pattern. English puts the possessive before the noun (her message), but Hebrew often puts it after.
There is also a shorter, more formal/literary form:
- הודעתה = her message
But in everyday speech, ההודעה שלה is much more natural.
