[Grammar] unique/different from each other

[hhtt21]

When you are not busy, would you please explain the difference between "unique from each other" and "different from each other". Aren't they the same things?

[emsr2d2]

Things aren't unique from anything. They're either unique or they're not.

 

[hhtt21]

'Unique from each other' means nothing.

So, is that title wrong? Yes?

 

[Rover_KE]

Yes.

 

[emsr2d2]

The title is wrong because the phrase does not exist. Things can be different from each other. They cannot be unique from each other.
