Questions & Answers about יש חשש רציני.
יש is the Hebrew existential word meaning there is / there are.
So יש חשש רציני literally means something like:
- there is a serious concern
- there exists a serious concern
It does not mean has by itself. In other contexts, יש לי means I have, but that is literally there is to me.
Hebrew does not have an indefinite article like English a / an.
So חשש רציני can mean:
- a serious concern
- serious concern (depending on context)
If the noun were definite, Hebrew would use ה־:
- החשש הרציני = the serious concern
In this sentence, the noun is indefinite, so there is no ה־.
