or // Either or // Either or but not both // Either or else

Hello,

I came across 4 different usage of "or" phrases, and understanding the differences was basically getting the problem right/wrong.
Would be great to verify!

1) A or B => A, B, A & B
2) Either A or B => A, B
3) Either A or B (but not both) => A, B
4) Either A or else B => A, B


Thx

Not an instructor but I thought the following:

2. Either A or B = can also mean A & B (similar to your first scenario)

4. Either A or else B = I thought this mean ~A --> B/~B --> A. Meaning both CANNOT be out.
