So in what sense is 这是什？ Different in tone than saying 这是什么？
Likewise if you say 这本书是你的吗？ Is saying 这么本书是你的吗？ Less aggressive?
这么大 I can see that in this sentence there is a difference than if you were to say 这是大。

这本书么是你的吗？

这是什 is a wrong sentence. Coz in this case, 什么is a word not '么' as a particle. Neither 这么大/那么可怜。这是大is wrong.
