Breakdown of במלתחה יש פריטים עונתיים.
Questions & Answers about במלתחה יש פריטים עונתיים.
יש is the Hebrew existential word for there is / there are.
So the structure is:
במלתחה יש פריטים עונתיים
= In the wardrobe/cloakroom, there are seasonal items
A useful point: יש does not change for singular vs. plural. You use יש with both פריט and פריטים.
In this kind of sentence, Hebrew usually does not use a present-tense verb like English is/are. Instead, it uses יש to express existence.
So English says:
There are seasonal items...
Hebrew says, more literally:
There exist seasonal items...
That is completely normal Hebrew.
