So on and so on and so forth etc

[mrmvp]

Do "so on" and "so on and so forth" and etc mean the same?

My understanding is that etc is the formal ones.

I struggle among these words/ phrases.

Those are informal oral expressions. I wouldn't use them in writing.

Note my corrections above. Why don't you give us a few sentences in which you're not sure which to use, and telling us in what context you want to use them?

Thank you @emsr2d2. I believe both "so on" and "so on and so forth are used in spoken English, while etc is formal in writing.
