This is the 925th most frequent Persian word.
بچه
Child or kid.
Here, 'بچهها' refers to 'the children', indicating multiple young individuals, with 'ها' being the plural marker in Persian.
بچهها در حیاط بازی میکنند.
The children are playing in the yard.
In this case, 'بچه' refers to a single child, used as a noun to describe a young person.
این بچه خیلی باهوش است.
This child is very intelligent.
The word 'بچههای' again shows plurality due to 'های', and it implies new acquaintances who are younger individuals.
