"the opposite of a statement is also true" can be said as "vice versa".

Is there a way to say "the opposite of a statement is not true"?

  • Unidirectional or non-conversely. – skullpatrol Aug 14 '14 at 10:36

A affects B, but not the other way around.

A affects B, but not the converse.

A affects B, but not reciprocally.

When the opposite is true:

Jasper likes Lauren, and vice versa.

When the opposite is false:

Jasper likes Lauren, but not vice versa.

This simple negation works well.

I'm not a Latin expert but how about "vice non versa"
