the meaning of たまに and んだ


たまに would mean occasionally/once in a while right?

how can we translate んだ in this context? or is it just an expression? if the
translation is wrong, do tell me.

> Text: たまにはなプレゼントをもらっていいと思うんだ。  
>  Translation: I think it is okay to receive present once in a while

よろしくお願いします！




Yes たまに means "occasionally."

んだ at the end of the sentence is not related to たまに. This んだ is the
colloquialism for のだ, which is often called _explanatory no(da)_. In your
sentence, んだ is not necessary but used for mild emphasis. Most of the time you
don't have to translate this のだ explicitly.

By the way, the な after たまには is one of the masculine [filler
particles](https://japanese.stackexchange.com/a/14924/5010) which do nothing
semantically.
