Other possible terms that could be used, depending on the context, include:
* "Tzimmes": This word can be used to describe someone who is overly enthusiastic about a particular topic, especially if it's considered unusual or geeky.
* "Yiddishe kop": This literally translates to "Jewish head" and can be used to describe someone who is smart or intellectual, but also a bit out of touch with social norms.
* "Boker": This word can be used to describe someone who is awkward or clumsy.
Ultimately, the best way to translate "nerd" into Yiddish would be to consider the specific context and choose the term that best conveys the intended meaning.
