Questions & Answers about הבדיחה שלו הייתה מצחיקה, וגם אני צחקתי.
ה־ is the Hebrew definite article, equivalent to the in English.
So:
- בדיחה = a joke
- הבדיחה = the joke
In this sentence, הבדיחה שלו literally means the joke of his, which is how Hebrew commonly expresses his joke.
Modern Hebrew usually expresses possession with:
noun + possessive word
So:
- הבדיחה שלו = his joke
- literally: the joke his / the joke of his
This is very common in everyday Hebrew.
A useful thing to notice: שלו refers to the owner, not to the noun being possessed. So:
- שלו = his
- שלה = her
Even though בדיחה is a feminine noun, you still use שלו if the owner is male.
