Sentence using 是……的 vs sentence using 很 This might seem a duplicate question, since beginers have a lot of doubt about not using 是 instead of 很 as in 我很好, but there's nothing related to what I'm asking here. At least I haven't found anything.

What does a native speaker think about the difference between a sentence using 是...的 and the same one using 很? For example:

这本书是新的。
这本书很新。

商店的衣服是贵的。
商店的衣服很贵。

Thank you.
是…的 is used for emphasis. In this case, it is used for contrasting.

这本书是新的: This book is new (contrasting old).

这本书很新: This book is new (neutral or normal case).
