I think correct usages of "and" and "etc." are:
A, B, C, and etc.
A, B, and etc.
But the example usage of "or" and "etc." I found in my dictionary is:
A or B, etc.
Why it is not:
A, B, or etc.
in the same way as "A, B, and etc." or as "A, B, or C"?
And when there are A, B, C, is the following correct?
A, B, or C, etc.
And if I omit the "or", which meaning do I get?
- A, B, etc.
- = "A, B, and etc."?
- = "A or B, etc."?
- A, B, C, etc.
- = "A, B, C, and etc."?
- = "A, B, or C, etc."?
