I'm not sure how to formulate this question, but some words bother me. Here's
a sentence for you :

> 彼女はまだ **ぶつぶつ** と呟いている。

I often see these kinds of words and sometimes, like this one, I can't find
what it could mean. My dictionary says "grumble, mutter" and so on, but isn't
that what 呟く means? Then, how do you use these words? Can these type of words
be translated or are they just part of the Japanese language without being
able to translate them into English? I feel like they can't be translated at
all.
