Is "我们的老师不是旧" acceptable?

[KX3.]

It is unacceptable here. 旧 is generally for non-living things and 是 is not used in this kind of sentences; knowing whether or not something is suitable for a sentence, I think, is something that comes with practice and exposure to the language. However, if this is part of a longer sentence, it may be correct, e.g. 我们的老师不是老，而是善忘 or even when, for example, correcting someone, e.g. 我们的老师不是“旧”，而是“老”。 There are many ways to put this, these are what came to mind.

谢谢！

[Ayose...]

Why is "我们的老师不旧“ not accepted? What's the difference between 老 and 旧 anyway?

[eliseree]

旧 is for objects like cupboards, houses etc 老 is for living things like 老爷爷 老人
