Thank you for pointing that out. Do you know any modern idioms? I couldn't remember any but sayings. I was looking up sayings but a synonym is idioms though they are not perfect synonyms. That last part was just a joke. Mind the lack of "/s". I do apologize for my "mistakes". However OP asked about sayings and those "terms" classify as such. I could not find any modern idioms so I went with sayings as per OP's request. Yet I have recognized the difference, I apologize secondly for not explaining myself clearer. As for the meanings, that is what is colloquial in my experience and that is how they are used sometimes, rather than just the origin, which I could have added in there. I apologize for not adding the true origins as I was going off of straight knowledge and experience using them and hearing them used. Sayings, like words can evolve over time. Thank you again for the observations.
