Questions & Answers about בקערה הזאת יש גלידת שוקולד, ואני רוצה עוד כפית.
Because ב־ is a prefix meaning in. In Hebrew, common prepositions attach directly to the noun.
When ב־ comes before a definite noun with ה־, they contract:
- ב + הקערה → בקערה
So בקערה הזאת means in this bowl. The definiteness is still there; it has just merged into the form.
In Hebrew, demonstratives like this and that usually come after the noun:
- הקערה הזאת = this bowl
- הספר הזה = this book
So the order is different from English. In your sentence, בקערה הזאת literally follows the Hebrew pattern in-the-bowl this.
A very common spoken alternative is בקערה הזו, which means the same thing.
