[Grammar] is hidden/was hidden

[Checkmate]

"James hid my book".

So is the result "my book is hidden" or "my book was hidden"?

I get confused when I see people often use "is hidden". Is it because "hidden" is an ongoing past participle?

 

[Raymott]

If your book was hidden (participle), it is hidden (adjective), and vice versa.

If my book was hidden but I found it afterward, then it is not hidden.
Is it possible?

Yes. Note that in BrE, it's "afterwards".

 

[Matthew Wai]

Then should I say 'My book has been hidden' if it is not found?

 

[emsr2d2]

It depends on the context.

My book was hidden behind the sofa by my little brother.
My book had been hidden by my little brother so many times before, that this time I found it in ten seconds.
What are you looking for? My favourite book - it has been hidden by my little brother again!

Note that in all those examples, the active would be much more natural: My little brother hid my book; My little brother had hidden my book; My little brother has hidden my book.

If your book was hidden (participle), it is hidden (adjective), and vice versa.

I used to consider past participle to be an adjective when it is in passive sentence. Was I wrong?

Early this year, on another forum, I asked a similar question about 'was/is + past participle', the OP may be interested in it, see https://www.englishforums.com/English/MyBicycleIsDamaged/bznwlz/post.htm#sc1903840
I also considered the past participle to be an adjective.

1. Written

2. Married

3. Banned

4. Taken

These participles are also used with present "To be" verb. But they are not continuous.

I have a question, are both participle and participle in adjective form are different when they are used with "To be" verb? And is that why it means differently?

 

[Matthew Wai]

I cannot make sense of your question. Perhaps you will get an answer from a teacher if you can explain it.

I'm not quite sure what you're saying. Both of the sentences use a form of 'to be', (was and is) and one is a participle and one is an participle adjective.
