And: Joins two similar ideas or things together.
Example: She likes apple and mango.
Nor: Joins two negative ideas.
Example: He does not like apples, nor does he like pears.
But: Shows a contrast or difference.
Example: I wanted pizza, but we had burger.
Or: Presents an alternative or choice.
Example: Do you want milk or juice?
Yet: Shows a surprise or contradiction.
Example: It was cold, yet she wore a dress.
So: Shows a result or consequence.
