I have a sister-in-law who is a wonderful person. I often tell her she is an angel. [?]

I see :) But the sense is still not quite the same.

The sense is never quite the same.

The English is definitely not interchangeable all the time.
Same language sentences shouldn't be linked unless they always have the same meaning, I think.

Also, TRANG has asked us to stop linking sentences in the same language for the time being.

Instead, you can leave a comment saying "Same meaning:".

Eventually, TRANG will come up with a system to link sentences with the same meanings that are in the same languages and will be able to link all such sentences with that comment, we hope.

See this issue on GitHub.

I still think the other mentioned links are misleading. I wouldn't use them interchangeably.

Please unlink them, if you want to.
