Talking To Oneself
Muttering To Oneself
noun
Remember how 独り means "alone"? Well, if someone is alone and saying something aloud, it constitutes talking to oneself.
独り言 means talking or muttering to yourself aloud, whether alone or in public. It can also refer to the words themselves — the things you say as you talk to yourself.
The reading for 独り is just the reading for 独り. The reading for 言 is an exception, though. It's ごと, which comes from こと. Just think that as you're talking to yourself you're telling yourself over and over to go to hell. You're mean to yourself, and you're also insane, which is why you keep saying that out loud to nobody but you.
