This isn't from an LSAT stimulus, but was a wording I came across in readings I use for practice. All other forms of "only" make sense to me and the conditional for this one also makes sense. But when you look at it as categories it seems "All A are B" and "All A are only B" are different in some way

Help; A are only B (meaning?)

Hi everyone,

How do I interpret "All A are only B"?

The conditional is clear, "no B then no A" but when thinking of it from a categorical perspective (like syllogisms etc) I'm no sure what it would look like or how to diagram.

Example:

"All diamonds are expensive"

"All diamonds are only expensive"

The first clearly allows for diamonds to be other things too, like beautiful, sturdy, etc.

But the second seems like it's saying that yes, all diamonds are expensive, but also that they're nothing else (so they're not beautiful or sturdy, just expensive)

Thanks in advance! This has confused me...

Are you sure?
